date/time from EXIF FE processing

[TanyaStere42]

Context

When uploading images as part of an encounter, users should be able to leverage the information from the photographs to simplify their data entry experience. We want users to be able to see a list of date/times from their photos, but it needs to come from the front end so we aren't dependent on a backend call to get the information. (needed for #793)

Requirements

Non-Functional Requirement

• PR needs to branch off of feature branch: submission_page

Functional Requirement

1. The dropdown is populated with datetimes from the photo EXIF
2. The user selects a datetime from this dropdown
3. The encounter date is populated with the datetime from this dropdown

maybe worth investigating submit.jsp and its use of javascript/exif.js through exifFindLatLon() (this would be frontend-only implementation).

otherwise could be BE api that can return MediaAssetMetadata on already-uploaded files (from #750)

do we intend to put those info to text input automatically so user don't have to enter them manually?

closing issue as duplicate of #794 now that this has been shifted to front end management
