py-phonenumbers: updated to 8.10.3

What's new in 8.10.3
Better documentation for length_of_national_destination_code to emphasise that \ 
not every number has one.
Removed unused code in the AsYouTypeFormatter: We no longer have numbers in \ 
formatting matching patterns, only \d.

What's new in 8.10.0
AsYouTypeFormatter changed to better choose between rules when dialling locally; \ 
previously we used the international rules when the national prefix was present \ 
since this would exclude the local-only rules. However, there are some numbers \ 
that are not internationally diallable that do use the national prefix, and this \ 
logic precluded formatting them correctly.
