core/localized-parsing: correctly handle group and decimal separator

Browse source 
We are usually showing pressures with localized group separator. And we made a
total mess out of things when then re-parsing those values. This caused us to
ignore start and end pressures in Subsurface-mobile when those were entered in
psi and included a group separator:

2,900psi was turned into 2.900psi which we then rounded to 0 mbar.

This fixes the problem by asking Qt to do the right thing instead of doing
stupid separator magic.
