Packaging

[LoicGrobol]

This is meant to fix https://github.com/UppsalaNLP/uuparser/issues/16 by adding Python packaging.

In order to conform to the structure recommended by the official packaging guide I have reworked the directories, that can be changed back (although I don't recommend it).

The installation can be tested with

pip install --no-cache-dir cython
pip install --no-cache-dir --extra-index-url https://test.pypi.org/simple uuparser

(--no-cache-dir to be correctly simulate a fresh install, separate Cython install required for Python > 3.7 until DyNet either release a new version integrating https://github.com/clab/dynet/pull/1608 or release Python 3.8 wheels)

Other changes:

• Remove the outdated Pipenv files pertaining to Python 2.7
• Add Github's Python gitignore
• Add a console entry point: once the package is installed, the parser can now be called directly from command line by uuparser
• Some string interpolation is done with f-strings, making this python >= 3.6, if this is an issue, it can be changed back.
• Rename the main source dir (and hence the package name) from barchybrid to uuparser, which seemed more fitting but this is purely cosmetic and easy to change
• Add a very basic smoke test to see if we can train a model on a tiny corpus (run with tox)
• Fix running with path containing space (which previously crashed the evaluation)

ToDo

• [x] update doc/readme
• [x] validate metadata
• [x] test if everything runs correctly (maybe add unit/integration/smoke tests along the way)
• [x] test release and install in a fresh env (via test.pypi)

@mdelhoneux (or someone else) Can you check if the metadata in setup.cfg are correct?

Yep looks good! This is great, thanks!

[LoicGrobol]

@mdelhoneux Cool, then unless there are specific things you'd like to test, this is ready to merge :-) I will delete the test upload on test.pypi and it will just need two commands to upload it on pypi, it's probably better if it's done by a maintainer than by me

[LoicGrobol]

Woops, found a tiny bug, please don't merge just yet

[mdelhoneux]

ok, cool!

Ok, ready to merge now!
