feat: add recovery point SEI message parsing for AVC and HEVC

Implement SEI type 6 (recovery_point) for AVC (ISO/IEC 14496-10 D.1.8)
and HEVC (ISO/IEC 23008-2 D.2.8), which have different syntax: AVC uses
recovery_frame_cnt (ue) plus changing_slice_group_idc, while HEVC uses a
signed recovery_poc_cnt (se).

Add exponential Golomb support to the bit-level types used by the sei
package: ReadExpGolomb/ReadSignedGolomb on bits.Reader and
WriteExpGolomb/WriteSignedGolomb on bits.FixedSliceWriter.
