Locale setting must be changed in b3parser.py

[fcbarbi]

Hello,

I get the message "locale.Error: unsupported locale setting" related to
File "/Users/XXX/Documents/dev/env/lib/python3.10/site-packages/b3parser/b3parser.py", line 446, in ler_arquivo
locale.setlocale( locale.LC_ALL, 'ptb' )

So I just changed from
locale.setlocale( locale.LC_ALL, 'ptb' )
to
locale.setlocale( locale.LC_ALL, 'pt_BR' )
