License has been updated to provide consistent expiration-related

information, factoring in hard expiration dates, grace periods, and

"expires soon" logic.
LicenseStatus constants have been renamed to go with

licensed/unlicensed terms and expired-based terms.
There are new classes, errors, and stubs for license update checks and

for license actions (which will include things like manually uploading a

license).
License check updates will be driven in an upcoming change. The process

involves asking the License Provider for a license check payload,

sending that payload to an outside server, then passing the result back

to the License Provider for processing.
Type hints have been updated to utilize | instead of Union.
Upcoming changes will begin to flesh out more of this, and add UI around

license displays.

Unit tests pass.
Tested this along with in-progress changes, verifying all these new

capabilities being stubbed out in this change.
