Notable changes:

• Bug fix: support chromosomes longer than 2Gbp (#59)

• EXPERIMENTAL feature: read splice scores from a file specified by--spsc
  and consider the scores during residue alignment. The feature makes it
  possible to apply advanced splice models and to improve miniprot alignment.

• Improvement: documented the C APIs and added an example program on using
  the APIs (#69).

This version produces alignment identical to v0.13, except for long chromosomes
or when the new feature is used.
