 Summary of the bug:
 libsvt_hevc has been added to ffmpeg, but there are a few issues:
 1) There is no documentation on ffmpeg.org
 2) There does not seem to be a *-params option for libsvt_hevc to specify
 encoder options in the ffmpeg cli. I have tried -svthevc-params, -svt-
 hevc-params, -svt_hevc-params, -svt-params.
 3) The embedded help ffmpeg -h encoder=libsvt_hevc lists a -tune
 parameter. This parameter is accepted by the cli, but it shows as
 deprecated and ignored.
 4) libsvt_hevc has an encoder option to disable loop filters -dlf 1, but
 that is not accepted, nor is a -deblock encoder option

 How to reproduce:
 Compiled with ffmpeg windows build helper script. Cross compiled on linux
 kubuntu 22.04 lts.
