* Added `-d` command line option that makes `-a`/`-k`
deterministic in the way alignments are reported. This
deterministic mode runs much significantly faster than `-a` and
consumes less memory. It not yet strictly better than `-a` when
considering alignments found. (PR #520, 521)
* Add support for selecting AVX version at runtime on x86_64/amd64
CPUs. (PR #515)
