Adjust the decoding of the files that are given so that a canonicalize

happens first, which will examine the incoming encoding, and decide the
neccasary decoding types needed to get the final resultant string and
then use these normalized decoding types to actually do the final decode.

Also change the name of the config key that is looked up to 'write_files'
since 'files' is pretty generic and could have clashes with other modules.

Add an example that shows how to use this in the different encoding formats
that are supported.
