* Add VPX improvements from pion-mediadevices - Add vpx_image.go: VpxImage wrapper for vpx_image_t with convenient methods - Move BitrateTracker to vpx package: More specific to VPX codec usage - Add bitrate_tracker_test.go: Test coverage for VPX-specific bitrate tracking - Remove generic codec-level BitrateTracker: Replaced by VPX-specific version These changes improve VPX codec functionality and organization by: 1. Adding image handling utilities specific to VPX 2. Providing better bitrate tracking for VPX codecs 3. Improving code organization by moving VPX-specific code to VPX package * Revert bitrate tracker changes - Remove vpx-specific bitrate tracker files - Restore original codec-level bitrate tracker and test - Keep only the vpx_image.go addition from pion-mediadevices * Add comprehensive unit tests for VpxImage - Add vpx_image_test.go with full test coverage for VpxImage wrapper - Test interface compliance and constructor behavior - Test nil pointer handling (documents expected panic behavior) - Test common video format constants and plane indices - All tests pass and integrate with existing VPX test suite This improves test coverage for the new VpxImage utility from pion-mediadevices. * Add comprehensive unit tests for VpxImage - Add vpx_image_test.go with full test coverage for VpxImage wrapper - Test interface compliance and constructor behavior - Test nil pointer handling (documents expected panic behavior) - Test common video format constants and plane indices - All tests pass and integrate with existing VPX test suite This improves test coverage for the new VpxImage utility from pion-mediadevices.
