Builds the package and publises it to PyPi
Increasess the pacth number by one, in the 'setup.cfg' file, unless otherwise stated,
 before building.

Args:
    --current-version: Only reads and returns the current version from 'setup.cfg'
    --read-version: Same as '--current-version'
    rc: Release as a release candidate version (eg 1.2.3.rc1)
    dev: Release as a development version (eg 1.2.3.dev1)
    test: Same as 'dev'
    major: Increase major version by one and set minor and patch to zero.
        e.g: 1.2.3 becomes 2.0.0
    minor: Increase minor version by one and set patch to zero.
        e.g: 1.2.3 becomes 1.3.0
    -y: Auto-confirm, i.e. Do not require manual confirmation of version

Todo:
    * Simplify, not modify the version in 'setup.cfg' but just use as input
