Update bank files - Fixes #1

This pull request updates the bank files to mirror the files in the original implementation (http://cpansearch.perl.org/src/SBURKE/Text-Unidecode-0.04/lib/Text/Unidecode/)
all these initial chars don't seem to match the Perl chars. It looks like you are now using empty strings here instead of the actual chars. the previous code was using the real chars for some of them (which is why one of them includes a newline).

My suggestion would be to use ``"\x01"`` and so on instead. It will be more readable than putting the invisible control chars directly. Respecting the same rule than Perl Text::Unidecode saying that all 7bits chars are left untransformed
