[IMP] barcodes: controller use the elaphe lib to generate barcode

[jefmoura]

Description of the issue/feature this PR addresses:
There is a framework to generate barcode, useful in many cases, e.g. if I want to generate Aztec/DataMatrix/Pharmacode barcode or many other types, I have these options in the elaphe library to use. The elaphe is a python binding of Barcode Writer In Pure PostScript. This framework provides a lot of settings to customize and create a barcode, just passing this information as options in the generating method.

Current behaviour before PR:
The current barcode generating method in Odoo uses the Reportlab and if I want to generate a Data Matrix code I need to update the Reportlab library to 3.3.0 version, but if I want to change the version/format I can't because it doesn't provide these options. This is only one of much more examples that we can find.

Desired behaviour after PR is merged:
Keep the current behaviour only adding more settings and options of barcode types, initially.

Hi @antespi @dreispt
I created this PR based on another PR that I have done on Odoo repository #13085.
If someone can check, I think these changes are useful for community.
Thanks!

Hi @jefmoura, thank you for taking this initiative. However, it is out of scope for OCB IMHO. We also strife to be 'stable' although we may include bugfixes that require a module upgrade. But injecting new Python dependencies is quite something else. I am sorry to learn from the upstream PR that Odoo won't take this either.
👎 therefore.

Ok @StefanRijnhart
Thanks for your feedback.
