Media agent for HLS JS v2.1.0

New features

• Added VegaTracker, an HLS.js tracker for Amazon Vega (Kepler / Fire TV class) devices. Import it via the new @newrelic/video-hls/vega subpath entry point. VegaTracker extends HLSTracker and routes telemetry through the connected-device pipeline instead of the browser pipeline. Ships as both CJS and ESM.

Bug fixes

• Corrected the tracker name reported by VegaTracker from 'vega-hls' to 'hls' so that the trackerName attribute in New Relic events matches the expected value.
