Server dependencies

[afrubin]

mavedb-api has a couple of optional dependency categories, dev and server.

The server dependencies are required to run the database, but not required to use the models for projects like MaveTools.

It looks like some of the recent dependencies for mapping VRS variants (hgvs, biocommons, cdot, others?) are in the core dependencies, but they should probably be in server. Does that sound right?

If the project has now outgrown this structure we can certainly revisit the way dependencies are managed.

This is still causing problems with the current version, due to the biocommons hgvs package being required, and it requiring pycopg2:

      Error: pg_config executable not found.

      pg_config is required to build psycopg2 from source.  Please add the directory
      containing pg_config to the $PATH or specify the full executable path with the
      option:

          python setup.py build_ext --pg-config /path/to/pg_config build ...

      or with the pg_config option in 'setup.cfg'.

      If you prefer to avoid building psycopg2 from source, please install the PyPI
      'psycopg2-binary' package instead.

      For further information please check the 'doc/src/install.rst' file (also at
      <https://www.psycopg.org/docs/install.html>).
