Microhapdb

Fixed
- Corrected a copy/paste error (see 33).

Added
- Marker definitions and allele frequencies for a 40 microhap panel presented at ISFG 2019 (see 25).
- Marker definitions and allele frequencies for 27 microhaps published in a 2015 *Legal Medicine* paper (see 31).
- Marker definitions and allele frequencies for 11 microhaps published in a 2019 *FSI: Genetics* paper (see 32).

Changed
- Replaced all references to `locus` and `loci` with `marker` and `markers` in the main code base (see 23).
- Huge overhaul to the database build procedure, the CLI, and the Python API (see 27).

Added
- Marker definitions and allele frequency data for 16 microhaps from a 2018 *FSI: Genetics* paper (see 14).
- Function to compute SNP positions from microhap locus ID (see 18).
- A function to compute standard internal MicroHapDB ID for a single label or list of labels (see 9ec1e93735);
any combination of ALFRED, LOVD, and MicroHapDB identifiers are valid input.

Changed
- Replaced pip/PyPI installation instructions with bioconda installation instructions (see 14).

Fixed
- Corrected DB build and coordinates (see 15).

Changed
- New command-line interface.
- New Python API.
- New database based on an updated table of 198 microhaplotype loci across 96 populations from ALFRED.

Fixed a bug with testing the installed package.

Fixed a bug with distributing non-code files.
