  ARM64 NEON SIMD impl. of prog. Huffman encoding
  
  This commit adds ARM64 NEON optimizations for the
  encode_mcu_AC_first() and encode_mcu_AC_refine() functions used in
  progressive Huffman encoding.
  
  Compression speedups for the typical set of five libjpeg-turbo test
  images (https://libjpeg-turbo.org/About/Performance):
  Cortex-A53: 23.8-39.2% (avg. 32.2%)
  Cortex-A72: 26.8-41.1% (avg. 33.5%)
  Apple A7:  29.7-45.9% (avg. 39.6%)
  
  Closes #229
