Add a new Model, it's the QSortFilterProxyModel that accepts
functions to filter / sort. so instead of creating a new class
for each different sorting (overkill), now we can just create
a function and pass to this class. I'll rework the filtering
system of subsurface to use this - in the meantime I've created
this to ease the creation of another filter: the dive sites
by gps coordinates.

So far, add_segment() returned a tissue tolerance (i.e. ceiling)
computed just in its return statement. This tissue_tolerance
needed to be dragged around until it was needed or be dropped
if not needed at all.
As for VPM-B, this ceiling computation is a bit expensive, this patch
calls the computation function tissue_tolerance_calc() when the
value is actually needed and not before.
This changes the signature of some functions.

and not some time before and store the result in a global variable.
This stores only the bottom gradients and computes the Boyle compensation
when computing the allowed ambient pressure.
As the Boyle compensation needs a reference ambient pressure, to find the ceiling,
we have to iterate this computation until the reference pressure is close enough to
the ceiling.

A real ceiling is the ceiling calculated when the ambient pressure is at the
ceiling. As such, the Boyle's law compensation should be done against the
ambient pressure at the ceiling. Instead of doing an iterative calculation,
take the lesser ambient pressure of the ceiling of the previous sample, and the
depth of the current sample.
This approach gets rid of "blips" in the calculated ceiling due to a step in
Boyle's law compensation during ascent. In limited testing, it also appears to
avoid creating a ceiling deeper than the calculated plan in most cases.

If adjacent samples at times t0 and t1 are greater than time_stepsize apart,
this for loop steps through the time between samples to calculate tissue
tolerance incrementally at each intermediate time, j, (and interpolated depth).
If the difference between t1 and t0 is not a multiple of time_stepsize,
immediately before the final increment time_stepsize needs to be reduced to
t1 - j so that j = t1 in the final increment.
This is necessary when:
t1 - j < time_stepsize (i.e. we are about to start the final
increment, and time_stepsize needs to be
reduced), and
j < t1 (i.e. we didn't just do the final increment -
without this condition time_stepsize would be
set to zero, leading to an infinite loop)
Previously, the check was (j - t0 < time_stepsize), which always returns false.

Assume your V2 file contains two locations with different name but
identical GPS location. "Blue Corner" and "Blue Corner, Palau". And you
have many dives there.
When reading a V2 file the GPS is read first and a dive site is looked up
based on that. Let's assume the lookup by gps finds "Blue Corner, Palau".
Now every time we get the "Blue Corner" site in the V2 file we look up
the GPS, get "Blue Corner, Palau" as dive site, then read the name "Blue
Corner" and say "oops, different site" and create a new one. Resulting in
several dive sites named "Blue Corner" with identical GPS but different
UUID (as we add the dive time into the SHA for the deterministic UUID).
With this commit, if we have a dive site that matches the GPS but has a
different name, we check if we happen to have an exact match for the dive
site information from the XML file (and use it, if we have it) before
creating a new dive site.

Inspired gas loading equations depend on the partial pressure of inert gas in
the alveolar.
P_alv = (P_amb - P_H2O + (1 - Rq) / Rq * P_CO2) * f
where:
P_alv alveolar partial pressure of inert gas
P_amb ambient pressure
P_H2O water vapour partial pressure = ~0.0627 bar
P_CO2 carbon dioxide partial pressure = ~0.0534 bar
Rq respiratory quotient (O2 consumption / CO2 production)
f fraction of inert gas
In our calculations, we simplify this to use an effective water vapour pressure
WV = P_H20 - (1 - Rq) / Rq * P_CO2
Buhlmann ignored the contribution of CO2 (i.e. Rq = 1.0), whereas Schreiner
adopted Rq = 0.8.
WV_Buhlmann = PP_H2O = 0.0627 bar
WV_Schreiner = 0.0627 - (1 - 0.8) / Rq * 0.0534 = 0.0493 bar
Buhlmann calculations use the Buhlmann value, VPM-B calculations use the
Schreiner value.

In other implementations of VPM-B, surface_tension_gamma and
skin_compression_gammaC are taken as 0.0179 N/msw and 0.257 N/msw respectively.
We do pressure calculations in bar, not msw, so our gamma values need to reflect
that. Previously we had used 0.179 and 2.57, which are close but not quite
correct (10 msw == 1.01325 bar).
