libhtscodecs2 binary package in Ubuntu Focal riscv64

 This library implements the custom CRAM codecs used for "EXTERNAL" block
 types. These consist of two variants of the rANS codec (8-bit and 16-bit
 renormalisation, with run-length encoding and bit-packing also supported
 in the latter), a dynamic arithmetic coder, and custom codecs for name/ID
 compression and quality score compression derived from fqzcomp.
 .
 They come with small command line test tools to act as both compression
 exploration programs and as part of the test harness.
