Michael Niedermayer 88b676105d avcodec/prores_raw: Check bits in get_value()
The code loads 32bit so we can at maximum use 32bit

the return type is also changed to uint16_t (was requested in review),

no path is known where a return value above 32767 is produced, but that was not exhaustively checked

Fixes: runtime error: shift exponent -9 is negative
Fixes: 439483046/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_PRORES_RAW_DEC_fuzzer-6649466540326912
