HEVC Range Extensions conformance fixtures

These fixtures come from the electronic attachment to ITU-T H.265.1 (10/2018), the conformance specification aligned with ISO/IEC 23008-8. Table 4 identifies the Sony GENERAL_*_RExt streams and their required profiles.

The .bit files are the original Annex B conformance streams. Each _frame0.yuv file contains the first decoded picture extracted byte-for-byte from the corresponding published planar reference output; it was not generated by ImageSharp.

HevcPictureDecoderTests.DecodeOfficialRangeExtensionsPictureMatchesPublishedDigest limits each stream to its first independently coded picture, adapts that picture to the bounded hvc1 item contract, compares every reconstructed sample with _frame0.yuv, and verifies the published decoded-picture MD5 value for every present plane.

The retained matrix covers the ImageSharp 8, 10, and 12-bit still-image precision boundary across monochrome, 4:2:0, 4:2:2, and 4:4:4. Tool-specific H.265.1 streams remain necessary before every exposed Range Extensions tool can be marked complete.
