Add github continuous integration workflow

Based on these continuous integration tests in client-superstaq

Not sure what to do about this failing type check:

./checks/mypy_.py passes for me locally (including from a fresh environment)

Which package are you using that has the google dependency in site-packages that mypy is trying to check?

i got the same error. it goes away if you uninstall types-protobuf after running mypy once

it's picking up on this import in cvxpy, which is only relevant to cvxpy[ortools] (and so the package isn't required otherwise): https://github.com/cvxpy/cvxpy/blob/ad6cafb117d24f82e094147e07a5f77a022ad1a8/cvxpy/reductions/solvers/conic_solvers/glop_conif.py#L49

the quick fix is to disable the install_types option for mypy (and add any relevant types- packages to the dev requirements). imo this is a mypy bug though

[richrines1]

apparently this is a known issue python/typeshed#11254

the best solution is probably just to pin

types-protobuf <= 4.24.0.4

for now (and unpin once that issue is resolved)

Awesome that worked! Thank you @richrines1!
