Add typemap processing in config file

Typemap processing allows files to be identified as binary and avoid possible corruption together with CRLF processing.
E.g. add the following to config.yaml file:

typemaps:
- binary //....ini
- binary //....uasset
- binary //....umap
- binary //....pdb

Add --convert.crlf option to convert CRLF to just LF for text files

Where files are of base type text, then this option will do EOL conversion.
Useful when exporting from Plastic SCM running on Windows.
