0.1.2 - arrows on LEDs, smaller output

Starting with this release, source .tar.gz and .whl distribution files can be found in the dist/ folder on the root of this repository.

Additionally, LEDs now have arrows pointing out of them, and SVG files are a good bit smaller now because the coordinates have had their trailing .0 dropped and/or rounded to 2 decimal places instead of something like 10 decimal places.
