Float offset

[FynnBe]

closes #280

enforcing that offset is a multiple of 0.5

The changes look good, but the tests now all fail. Do we maybe enforce float values with these changes?
That should not be the case! Maybe we need List[Union[float, int]]?

[FynnBe]

ints are perfectly valid floats so we don't need any Union there. The whole list of floats threw the initial validation off...
anyhow, this new error ModuleNotFoundError: No module named 'conda._vendor.auxlib' is very obscure and seems unrelated!?

I restarted the tests. Let's see if it happens again, but yes it looks unrelated.

Ok, it's still failing.
@k-dominik any idea what might cause the test failure in the conda-build test:

  File "/usr/share/miniconda/lib/python3.9/site-packages/conda_build/environ.py", line 483, in meta_vars
    d.update(get_git_info(git_exe, git_dir, meta.config.debug))
