All sessions broken

[Eric Pettersen]

The changes to support tinyarray now cause all session restores to fail with:

init() got an unexpected keyword argument 'raw'

[Eric Pettersen]

The session might need to contain a structure.

[Greg Couch]

This is due to both the msgpack-python and msgpack packages being installed. msgpack replaces msgpack-python with a newer. backwards compatible, API. Not sure yet where msgpack-python is coming from.

[Greg Couch]

msgpack-python was explicitly being installed in prereqs/msgpack, in addition to msgpack being installed in prereq/pips/. Now, only install the one in prereq/pips (from pypi). To fix today's daily build, do "ChimeraX.app/bin/python3.6 -m pip uninstall msgpack msgpack-python" followed by "ChimeraX.app/bin/python3.6 -m pip install msgpack".
