Internal JIRA issue: https://jira.corp.adobe.com/browse/VA-4808

High-level changes:
* create datatypes to be used in 2 fieldgroups: mediacollection and mediareporting
* deprecate the media.schema.json and use the new schemas for a better experience for our clients

Start by reviewing the listed schema files and the linked JIRA context; no tests or entry points are identified. Map the proposed datatypes to the mediacollection and mediareporting fieldgroups, then verify that media.schema.json is deprecated and the affected schemas use the new replacements.
