Reason for change:Adding the support to detect EarlyAvailablePeriod to Queue Content Protection
Risks: Medium

Pull request overview

Adds support in the DASH MPD fragment collector to detect non-VSS Early Available Periods (EAP) in live manifests and pre-queue DRM content protection (license prefetch/rotation path), guarded by a new config flag.

Changes:

• Introduces processLicenseFromEAP config and wires manifest processing to call ProcessLicenseFromEAP() for live MPDs.
• Adds GetEarlyAvailablePeriods() detection + queues content protection for the detected early period’s adaptation sets.
• Extends unit-test infrastructure (mocks/fakes + new test cases) to validate early-period detection and license queueing behavior.
