Slow import due to pkg_resources

[Ristovski]

Importing pkg_resources is slow (see pypa/setuptools#926 et al).

As a demonstration, dropping the following import pkg_resources and hardcoding the version improves the import times significantly, from ~400ms down to ~20ms.

ripgrepy/ripgrepy/__init__.py

Lines 8 to 11 in 3fc9092

	from pkg_resources import get_distribution
	import logging
	__version__ = get_distribution("ripgrepy").version

Baseline, argparse as example:

$ python3 -c 'import timeit; t = timeit.Timer("import argparse").timeit(number=10); print(f"{t:.3f} seconds")'
0.010 seconds

ripgrepy, pkg_resources version:

$ python3 -c 'import timeit; t = timeit.Timer("import ripgrepy").timeit(number=10); print(f"{t:.3f} seconds")'
0.397 seconds

ripgrepy, hardcoded version:

$ python3 -c 'import timeit; t = timeit.Timer("import ripgrepy").timeit(number=10); print(f"{t:.3f} seconds")'
0.019 seconds

Thank you for the great suggestion! It has been addressed for the next major release.
