Feature: implement support for the -T/--trim parameter

Provide support for trimming the object names on input and output.

After implementing this I suddenly remember that the standard might require that the whitespace before and after a valid object name are to be ignored.
This may be removed in the future and fixed in the library.
Additional investigation on how I want to handle this needs to happen first.

The standard is originally designed around ASCII, which only ASCII whitespace is considered whitespace.
This will probably have to be fixed to match the additional goals of the project in terms of whitespace handling.
