Handle new interface format keywords from NeuroConv 0.6.0

[rly]

Working on #957.

Address #957 (comment)

• Generates JSON Schema for interfaces using NeuroConv 0.6.0 which updates format: file -> format: file-path and format: directory -> format: directory-path among other changes.
• Updates GUIDE code to detect file-path and directory-path instead of file and directory for displaying a file selector vs directory selector
• Updates internal GUIDE code to use format: file-path and format: directory-path. I think I caught all the instances.

Alternatively, I could have converted the JSON Schema on read to change file-path back to file and not change the rest of GUIDE, but 1) I think file-path is more informative, and 2) that conversion feels less clean.

Other changes in the interfaces will be addressed in a separate PR to keep this one clean.

4. Sbx Imaging Interface accepts a new enum photon_series_type (OnePhotonSeries or TwoPhotonSeries, default: TwoPhotonSeries)
5. Video Interface accepts a new metadata key name (default: Videos)
6. Neuralynx Recording Interface now accepts ".ncs" files
