v0.3.0

• GiroCode on invoices: templates get document.payment_qr, an EPC QR code (SVG data URL) that banking apps scan to fill in the SEPA transfer: your organization name and IBAN/BIC, the total and the invoice number as reference. It is only filled for finalized invoices with a total above zero and an IBAN in the organization settings. The built-in templates do not print it; add it to your own template: https://openbill.dev/en/templates#girocode
• New Liquid filter iban prints an IBAN in groups of four (org.iban | iban).
• payment_qr is now a reserved key for document fields: a custom document field with this key is hidden by the GiroCode in templates.
• No changes to the compose files.
