Branch names with special characters lead to broken builds #67
Description
Since version 1.12.0, branch names that contain special characters, like feature/whatever, that are not allowed in version strings, cause broken builds. I've created a minimal example to demonstrate this behavior: https://github.com/mlangc/setuptools-git-versioning-version-parsing-bug-reproduction/tree/feature/whatever
If I run setup.py --version with the code from the link above, I get
Traceback (most recent call last):

packaging.version.InvalidVersion: Invalid version: '0.0.0.dev1+feature/whatever.1.cf8f98db'
Note that everything works fine, if I use setuptools-git-versioning==1.11.0 instead. As far as I can tell, this problem was introduced by 49c719a#diff-669acc32e6f1e51356caf8db37342593a3fa289dade13da5fc4132b1f8fb1452L567, since the new sanitize_version function throws exceptions for invalid version strings.
