I think so, feel free to make a PR.

Other modules that provide something like the above are called info()
or split() in python-stdnum.

From my understanding GS1-128 embeds a various numbers with an
application identifier prefix. If these numbers are interesting in
their own right (e.g. GTIN/EAN) having them in their own module would
be really nice (especially if extra validation there would be useful).
Parts that only handle a date or size should probably be part of the
gs1_128 module.

It would be really nice if you could provide an implementation for
this.

Thanks!
