Fixes bug #267 for voice parsing from match files

[sildater]

Thanks for looking into this!

this PR has several problems:

• the implementation of voice parsing were voices are encoded as score attributes "vXYZ" is not working. Currently all match files of the newest version get all voice attributes set to 1 (the reason it's not none is the code in lines 747-750 in importmatch.py). Please check what strings the number_pattern regex is matching. If the logic is not clear, just ask.
• it removes prior check for numbers (strings that only contain integers) in the scoreAttributeList. Are you sure this never happens in any match file? Unless you know for certain that the current implementation is unused or your replacement refactors the use case, please do not remove or change used code and cases from the library!
• minor point but it'd still be nice: some unittest for different versions of match files would be great.

doesn't work yet. not automatically tested. removes potentially used functionality.

The tests were not launched because the initial push was made for the main branch and then changed, an additional commit even an empty one, has to be made to launch the tests. I will do that.

Thanks! What I meant is the functionality in the PR is not addressed in a unittest.
