[PATCH] Index used cylinder properly on divelogs.de export

[Miika Turkia]

The wrong O2 percentage was due to not referring to the correct cylinder
but grabbing any o2 value in any cylinder. While fixing this, I noticed
that also end pressure was missing the cylinder selection, so fixing
that as well.

Fixes #626
