Data Import from MCMICRO path (local/remote) for Minerva Analysis Tools

[kruegert]

Instead of specifying image, mask, and single-cell csv file locations for the project import individually, allow the user to point to an mcmicro output folder.
Upload then follows mcmicro subfolder and file naming conventions.

• Added form validation (client side - if fields are filled, and server side - if paths/files are existing).
• Added mcmicro mode to load all from mcmicro output folder, following naming conventions

Plan to add mcmicro bulk upload (given a parent folder scanning all mcmicro subfolders) for cohorts.
