Speed-up f-string tokenization by reducing strlen() calls #203

This took a bit of longer than expected since multiline f-strings did not work with basic arithmetic but I think the current form should work (would love if you folks can also double-check it).

Do we have tests that fail if we introduce some bug here?

We don't but I've manually checked test_fstrings numbers (it was 87 failures before, 87 failures now).
