Run test suite for gale transform

[kliem]

We add a method that checks gale transforms and it's inverse.

We also fix two # long time flags for the snub cube:

• one is missing spaces,
• the other test certainly doesn't take 30 seconds anymore (I need about 2).

Depends on #29898
Depends on #29903
