Add port of unpack_and_2bcompress

Rodrigo Causarano requested to merge aws-graviton/SVT-AV1:glpuga/port_svt_unpack_and_2bcompress_c into master

Description

This MR vectorizes in NEON the functions below by porting the SSE4.1 version of the same algorithms:

  • svt_compressed_packmsb_c
  • svt_enc_msb_pack2_d
  • svt_unpack_and_2bcompress_c

The datasets for the 8 bit files can be sourced from:

Merge method

  • Allow the maintainer to squash and merge when PR is ready to create a 1-commit to the master branch. The maintainer will be able to fix typos / combine commit messages to create a more readable 1-commit message or use whatever is stated in the 'Description' section
  • I will clean up my commits and the maintainer shall use 'rebase and merge' to the master branch
