Xrd-image-util

Advanced line ROI's.

Added
- Line segment ROI that is defined by two enpoints in 3D space
- Graphical LineROI tool in the ImageGUI

First official release

Added
- Lazy loading for Scan class variables.
- RectROI class - Creates a rectangular region of interest that can present output from a series of scans.
- Line Data GUI: Monitor variable. If selected, y-axis variable will be divided by the monitor.
- Image Data GUI: Rectangular ROI's with controls.

- Line data GUI variable selector now holds list of all variables available in a catalog. Scans that do not include a selected variable name are blacked out and cannot be plotted.

Basic GUI for viewing 1D Catalog data.

Added
- Catalog.view_line_data(): A function that displays an interactive widget for viewing various 1D curves for all Scan variables in a given Catalog.

Added
- Catalog.list_scans(): A print function that returns metadata about every scan in a catalog
- Catalog.get_scan(scan_id): A scan retrieval function that uses a simple scan ID (rather than the UID) as a parameter
- Catalog.get_scans(scan_ids): A scan retrieval function that returns a list of scan objects
- The ability to create reciprocal space maps (RSM's) for 4-circle geometries. This step is completed automatically when a `Catalog` object is created.
- Scan.grid_data(...): A function that creates a gridded, interpolated, and transformed 3D image with respect to a scan's RSM.
Changed
- Variables `bs_catalog` and `bs_run` have been renamed to `bluesky_catalog` and `bluesky_run`, respectively.
