GE2/1 compatibility and elimination of GE1/1-specific hardcoded constants

[mexanick]

Brief summary of issue

Current version of the code suffers from various GEM detector type specific constants being hardcoded and can't be used in a straightforward manner with the GE2/1

Types of issue

• Bug report (report an issue with the code)
• Feature request (request for change which adds functionality)

Expected Behavior

The software should work in the very same manner between GE1/1 and GE2/1

Current Behavior

Currently some of the methods are still working, but wasting the memory assuming GE1/1 electronics layout, others simply does not work properly due to mapping differences.

Your Environment

• Version used: tip of develop
• Shell used: bash
• Setup: GE2/1 integration stand
