Bug

zbar is an old library that is being removed from different Linux repositories.
I suggest that instead of make it a mandatory, we make it optional (via a try/except) and the read_qrcode throws an exception if zbar is not installed (as I see, it's used only for decoding the QR image).

Or (better), we replace it with something else, if exists.

Thanks for working on this. Helped a lot implementing ZATCA's e-invoicing :)

you have issue with invoice date timestamp
invoice date must be datetime as string not timestamp float..

datetime must be convert to string using this patch code:

invoice_date.isoformat()[:-6] + "Z",

Thank you for this package
Best regards,
