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).

- We add a dive while offline.
- On a different computer (here simulated by a different local cache) we
add a different file.
- Now we go back to the previous local cache (the one where we added a
different dive in the first step) and take that online (i.e., connect to
cloud storage). Now both of the new dives should have been added to our
data file.
This is a rather trivial test with no conflict and a straight forward
merge. We need to add a lot more test cases to make sure this works as
expected and doesn't leave the user with a corrupt state.
Ideally whatever happens, the user should never see an error...

Having random uuids seemed like a good idea, but there are several
situations where they really cause problems. One is merging dive file
imports from V2 logfiles. Another is testing such imports.
Instead of making the uuid random we now hash the name and add the
timestamp of the first dive associated with this dive site to the hash
(first in this context is "first encountered" with no guarantee that it is
the chronologically first). This way V2 imports create deterministic uuids
but uuid conflicts are still extremely unlikely, even if the user has
multiple dive sites with the same name.
