This creates a new codec id for mxf vbi_vanc_smpte_436M streams.
This makes it easier to use from other [de]muxers and bitstream filters.
It's just the data in Table 7 (starts on page 13) of:

They were not sorted before, sort using: LC_ALL=C sort --ignore-case
since that's what file-contents-sorter (added in next commit) supports.

This commit adds a ProRes RAW hardware implementation written in Vulkan.
Both version 0 and version 1 streams are supported.
The implementation is highly parallelized, with 512 invocations dispatched
per every tile, with generally 4k tiles on a 5.8k stream.
Thanks to unlord for the 8-point iDCT.
Benchmark for a generic 5.8k RAW HQ file:
6900XT: 63fps
7900XTX: 84fps
6000 Ada: 120fps
Intel: 9fps
Simple parser that only parses frame information.
This helps avoid requiring the software decoder on init to decode a
single frame, since the decoder can be quite slow.

Add check for the return value of av_packet_alloc() to avoid potential NULL pointer dereference.
Moreover, replace redundant av_free() with fprintf().

In general, a provider code corresponds to a company/organization, and
the name should be that of the company, not of a given feature.
The feature is signalled in the "provider oriented code".
The exception is HDR Vivid, where the code 0x0004 indicates the HDR Vivid
feature itself rather than CUVA (China UHD Video Industry Alliance),
according to the UHD World Associations 'HDR Video Technology Part 2-1
Application Guide to System Integration' document.

ITU-T T.35 provider codes are attributed by national bodies and it's
possible to have collisions across countries. This is why the country code
must always be checked as well.
Use if statements rather than nested switches which would be unreadable.

This should be done by fate.
This script already blocks security fixes (https://code.ffmpeg.org/FFmpeg/FFmpeg/actions/runs/1046/jobs/0)
IMHO its not good
1. to add commit message formating rules, never discussed or agreed
2. to expect developers to push commits trial and error style, make fate
can test this already and tell the devlopers before pushing, saving him
time
This reverts commit cc6ad703b4.
