Issues with epicscorelibs, pyca, whatrecord, pmgr

[ZLLentz]

• pyca is currently installed from conda-forge and built with a specific (but recipe unspecified) version of epicscorelibs that must be static for the install to work.
• whatrecord is currently installed from pypi via pip and built for the install against whichever epicscorelibs is present
• pmgr requires pyca and epicscorelibs and therefore its recipe keeps them in sync
• In this repo, we pin to a specific pyca build and a specific epicscorelibs version

This is a mess. Vague to-do:

• figure out the general problem: how to properly package epicscorelibs build/run dependencies on conda-forge
• do the above properly on conda-forge so at minimum we get the compatible core libs when we install, and with vague future hopes of having compatibility with multiple corelibs versions
• install pyca from source for the env builds to avoid this issue
• unravel pmgr's tight pinning so we can update properly without breaking pmgr's CI testing

whatrecord can be removed from this list after pcdshub/whatrecord#134 gets merged.

It will still require installation from pypi, at least until I feel like attempting epicsmacrolib on conda-forge

I think it's already ok actually and I did a bad by including it in the title. The conda installs here are the ones that appear to break things.
