forcing 4:3 fov in 16:9 resolution

hello hzqst i really like the r_adjust_fov 2 feature in the release but is it possible that you could make the same plugin for the default cs 1.6

Forgot to mention that it has already been implemented for both SvEngine and GoldSrc: https://github.com/hzqst/MetaHookSv/blob/main/docs/Renderer.md#widescreen-adapted-fov
