Memory Trace Network Plus Cleanup

[aqvining]

Hey All - Big update here. This mixes some of the quality of life stuff we discussed months ago with a final SiPS/Memory Trace network package. Sorry that I didn't this into more bite-sized pieces. Here's the overview

Changes to core PS package

• updated deprecated use of setuptools in setup.py
• Formatting fix and documentation in ECMS/01_Core
• Removed RLGL environment
• Removed Priming ECM
• lib helpers: I don't remember what the issue was, but there's a fix
• There's some metadata changes because at some point I forgot to clean notebooks before doing a merge.

SiPS/MTN Addtions
I won't go into detail on these, just summarize where things have been added

• New Library in ECMS: 03_state_estimators.ipynb
• New Library in envs: POMDPs.ipynb
• New Library in envs: Factorized_POMDPs.ipynb
• New Tutorial: learning_ps/Memory_Based_State_Estimators.ipynb (This may need some updating, but it runs)
• functions added to visualizations, transforms, and samplers. Some modifications to functions that were already being used in earlier versions of SiPS, but not in core PS.

I think that's all!

Updated code passes all checks. However, one of the conflicts was with an update to nbdev - I completed this update and was asked to migrate the library to a new set of conventions. These don't seem to have been too disruptive, but they don't use a settings.ini file - so I am unsure where/how to update a version number.

This PR also includes the changes to nbdev 3 + a bump to version 0.1.0
