Initial XPCS GUIPlugin

[ihumphrey]

Initial PR provides a basic interface for running 1-Time correlation and viewing the reduction data. This is not intended to be complete functionality; this PR represents an initial state of the XPCS GUI with known limitations.

• Added XPCS requirements to requirements.txt

• In setup.py, removed deprecated dependency_links and updated install_requires to pick up the PEP 508 URL requirement (scikit-beam)

• XPCS GUI allows 1-Time correlation calculation to be performed.

  • Can load in images and separately selected loaded data for processing
    • limitations: work still needs to be done on batch processing (selecting multiple data sources to process)
  • Results are shown in a plot widget that is tied to a tree view
    • Can select individual ROIs from processed data to plot
    • Fit is performed automatically and plotted with the checked reduction data

• Created APSXPCS DataHandlerPlugin to ingest processed XPCS APS data

  • loads and displays g2 fits, g2 error bars, and ROIs based on q
  • limitations: the raw data is currently not being ingested
