Tool generates incorrect platform tag in output filename when run on Linux when using wheel version >0.34.2

[hutchisr]

pywhlobf currently (as of 0.2.3) generates an uninstallable wheel on linux due to an error in the platform tag in the output filename:

As an example:

Running pywhlobf test-0.1.0-py3-none-any.whl dist will produce the output dist/test-0.1.0-cp38-cp38-linux-x86_64.whl. Attempting to run pip3.8 install dist/test-0.1.0-cp38-cp38-linux-x86_64.whl will produce the error ERROR: test-0.1.0-cp38-cp38-linux-x86_64.whl is not a supported wheel on this platform. because linux-x86_64 is not a valid platform tag, it should be linux_x86_64 (note the use of an underscore rather than a dash). Manually renaming the file to the correct pattern solves the issue.

This seems to be related to changes in wheel.bdist_wheel.get_platform in versions 0.35.0 and above.
