MVM: cross-match SVM catalog info in regions of MVM overlap

[stscijgbot-hstdp]

Issue HLA-741 was created on JIRA by Warren Hack:

Source catalogs generated as part of the SVM processing should be used, if available, to perform cross-matching analysis for regions of overlap between exposures in MVM layers where exposures from different visits overlap.  

The logic for transforming the source catalog positions into MVM positions and then identifying what sources (catalog rows) fall in the region of overlap will need to be developed for this analysis to be performed.  

Implementation of ways to visualize these results will be part of this ticket since it requires knowledge of how the results are generated and stored, and serves as the final product for the Q&A processing.

Need overlapping observations from differnet visits to use as test particle

NGC 1275 ACS/WFC F435W observations 10546_02 and 10546_04 MAST Link

FOV dominated by bright galactic source. Lots of nebulosity

PR 1405 handles the initial creation of the crossmatch analysis code up to including the step where the analysis results are written to a .json file. A forthcoming future PR will handle the actual visualization of the results.
