unify API for accessing databroker and provide implementation for other beamlines about ptycho_gui

[leofang]

See NSLS-II/PyXRF/pull/138 for how PyXRF does this.

I'm following up this thread (slowly!) @wen-hu, is this something that still interests you? For now I'm thinking to have a file called nsls2ptycho/core/CSX_databroker.py as a drop-in replacement so that we can switch to it in the GUI. If possible, can you show me how the following two code segments can be replaced for their equivalences at CSX?

I remember you showed me a Jupyter notebook long ago but I can't find it now. Plus you may have changed the practice in your recent experiments, so it'd also be nice for me to be updated.

Thanks!

It seems @NSLS-II-CHX also does some ptychography work? See NSLS-II-CHX/pyCHX.

The majority of this issue is resolved in #65. Closing this.
