Release 0.0.4

What's Changed

• Support for python 3.6 and 3.7 has been dropped (versions of python prior to 3.8 are considered end-of-life)
• Updated dependencies to most recent versions that support python 3.8+
• Added cgranges as submodule - this enables pybedlite to be published to pypi once again
