From: Christopher Degawa <christopher.degawa@intel.com>

svt-av1 v1.2.0 has deprecated vbv_bufsize in favor of using
- maximum_buffer_size_ms (--buf-sz)
- starting_buffer_level_ms (--buf-initial-sz)
- optimal_buffer_level_ms (--buf-optimal-sz)

and vbv_bufsize has not been in use since svt-av1 v0.8.6
