Add barcode generation capabilities to plugins

[wolflu05]

This PR adds barcode generation capabilities to plugins which enables custom formats.

The current built-in inventreebarcode plugin is used to generate the already existing JSON barcode format, but can also generate the short format described in #6612 (comment) (depends on how the plugin is configured) (can also parse this short format).

The previous barcode implementation allowed to create a non-brief variant of qr_code data, which was not used anywhere except in some tests, so I dropped this for now since it was not touched too after the initial implementation 4 years ago. Please tell me if this is actually being used somewhere, then we need to find a different solution.

TODO

• allow plugins to generate barcode data
• inventreebarcode plugin implement parsing for short format
• improve qr_code template tag to let the user specify the ECL
• improve tests
• improve docs
• bump API version
• PUI implement show QR code modal
• CUI use correct format for QR code modal

Closes #6612

This is ready for review now.

Very nice work; One small visual thing: Could we add some text above the barcode data so it is understandable what the barcode data is meant to be?

[SchrodingersGat]

@matmair this text is available here, below the barcode: is this what you meant?

@wolflu05 tested locally and this seems to work very well. Short barcodes integrate nicely with the app :)

Added now. Also applied your code review comments.

Short barcodes integrate nicely with the app :)

Yes, that's a very good system. Very easily extendable through barcode parsing plugins. Great base work.

[SchrodingersGat]

LGTM. @matmair any further thoughts on this?

[matmair]

LGTM, great work @wolflu05

[wolflu05]

Hm, the ci tests error seems strange, need to investigate that further tomorrow before we can merge this.

[wolflu05]

Ok, figured it out. This is now ready to merge from my side. (For detailed explanation, see #7648 (comment) )

[SchrodingersGat]

@wolflu05 very nice indeed. Thanks for your great work on this!
