RTD erroring

[lwasser]

Right now RTD when it builds is automatically erroring when it tries to resolve the conda envt to support documentation. A few options to tr

1. remove the conda envt and build via pip (this is actually working now)
2. pin everything to reduce how much it needs to resolve. it still seems to fail with man deps pinned and this is really challenging to maintain.

Right now it seems like the docs are building just fine wout the conda envt so i may go with this for now.

see pr #517
