Give ParsedWheelFilename a construct() method

[jwodder]

The method should take separate project name, version, etc. parameters and escape & combine them into a valid wheel filename.

• The method should canonicalize the project name and version.

  • Non-PEP 440 versions will result in an error.

• Characters in the build, Python, ABI, & platform tags other than Unicode word characters, Unicode digits, and (for the build tag) the period should either cause an error or be converted to underscores.

  • Add an option for controlling which one happens?

• construct() should take the Python, ABI, & platform tags as sequences of strings to be sorted and joined with periods.

  • Support omitting each option to default to "py3", "none", and "any", respectively?
  • It should also be possible (either through other arguments or a separate method) to specify the compatibility tags as a list of tag triples.
