Fixed race condition / bug where the check would modify the cmap of the font being checked. Deep copies the ttFont so that the cmap modifications don't trip up other checks. In our case, I saw com.google.fonts/check/soft_dotted crash because the cmap was changed while it was being iterated through. For the nuance between copy and deepcopy, see: https://docs.python.org/3/library/copy.html
Props to @Hoolean for correctly guessing and then spotting this issue from an awful stack trace in a one-off error.
