[PATCH] Don't ignore actual diveable mixes

[Anton Lundin]

Fist is really obvious. I quite regularly decompress using pure O2. Its
as good last decompression gas as you get.

The second is a bit harder. There are quite few that dive with 80%+
helium in there mixes but they exists, and there are real weirdos that
dive heliox, so they are actual diveable gases too.
