missing RPL compression types

Summary of the bug:
I've encountered multiple RPL (Acorn Replay Video) video files on old RISC OS CDs that ffmpeg doesn't support at all.
Sample file attached and more here: https://telparia.com/fileFormatSamples/video/acornReplayVideo/ (bluegreen, butterfly3, chimes, ducks2, parrot, voyager)
How to reproduce:
% ffmpeg -i parrot out.mp4 ffmpeg version 4.4.1 Copyright (c) 2000-2021 the FFmpeg developers built with gcc 11.2.1 (Gentoo 11.2.1_p20211127 p0) 20211127 [rpl @ 0x17dc7c0] Video format  is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented. [rpl @ 0x17dc7c0] Don't know how to split frames for video format . Video stream will be broken! [rpl @ 0x17dc7c0] Could not find codec parameters for stream 0 (Video: none ( / 0x0007), none, 160x128): unknown codec
Format of RPL files appears to be here: https://multimedia.cx/AE7doc.txt
Any chance support for compression type #7 could be added?
