Normalization steps

This library contains generic logic to normalize (string) data and transforms strings to URIs. It should be applicable to data from any source (GenBank, ENA etc).

Important: missing data should be missing or None! Do not fill in data by 'guessing'.

When data is malformed a warning should be logged and added to the warning list. Functions should be small enough to return only 1 warning!
