Render custom fields as barcodes

Feature name

Render custom field values as barcodes.

Feature function

Loyalty cards from various supermarkets and shops can already be stored as custom fields in Bitwarden.

It would be incredibly useful if there was a method to render these fields as barcodes. The Bitwarden mobile app could then be used when scanning these cards in the shops.

This would be preferable rather than having to rely on intermediary apps like Stocard - which might not be privacy oriented.

The custom field types could even be expanded to include a barcode type.

There already is a topic related to rendering these fields are QR codes but I believe their use case is different from this one.
