ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Sun Jan 10 19:22:59 2021 -0300| [9219ed213d10fb2ae13da15402f5acf35ffb25ba] | committer: James Almer

avcodec/cbs: constify decompose_unit_types

CBS doesn't change its contents in any way whatsoever internally, and most
users already set it to a const array.
