pypy3 is broken in ci

[nilsnolde]

I fiddled a bit yesterday:

• changed the build system to setuptools_scm for automatic versioning based on git tags
• added a workflow for automatic publishing on pypi

somehow that broke all kinds of tests in CI, none of the failures I could reproduce locally despite the same python version and workflow. the tests looked broken though, so I fixed them up.

now pypy3 is broken: https://github.com/gis-ops/routing-py/runs/5544884127?check_suite_focus=true

it seems to me that it tried to install a py27 version of typed-ast for pypy3.6:

ast27/Parser/tokenizer.c:17:10: fatal error: codecs.h: No such file or directory
       17 | #include "codecs.h"
          |          ^~~~~~~~~~
    compilation terminated.
    error: command 'gcc' failed with exit status 1

hey @nilsnolde wanna work for this issue !

Sure, feel free. Though might not be an issue anymore. Personally I’d start with letting CI run once with PyPy and then see.
