• Updated packaged htslib build to release 1.14
• README fixes #726 (thanks @veghp)
• Add option to force use of submodule deps (thanks @jnumm)
• Using recent guix shell support for building freebayes
• Added static build support with meson+ninja
• Started tracking freebayes performance in ./test/performance/benchmark.md
• Added matrix channel badge to README
• Added Pjotr Prins as maintainer in README and banner

The provided static binary is built against gcc 10.3.0 and htslib 1.12.
