Remove hard-coded information from the BTPS Screens

[slactjohnson]

Current Behavior

There's some information that's hard-coded into the BTPS screens, and is duplicated by information in btps.py.

Expected Behavior

Information is not duplicated.

Context / environment

The same (or similar) information is already build into btps.py . When updating the stage mapping I fixed it in the code but forgot to do it in the screen, which caused confusion. I want to prevent this in the future.

btps.py:

pcdsdevices/pcdsdevices/lasers/btps.py

Lines 661 to 714 in 665c1f4

Suggested Solution

Find a way to work the information present in btps.py into the screens. btps.py uses PVs, the screens use happi.... one method should be used, not both.
