## Description of the issue/feature this PR addresses:


The QR-Invoice is planned to land in June 2020. (as it was delayed)
Since it was developed

[IMP] l10n_ch: Swiss QR Invoice version 0200

Swiss QR Invoice with QR Reference (QRR) needs a special
IBAN named QR-IBAN.
A QRR is exactly the same as an ISR Reference.

* Add a new res.partner.bank type `qr-iban`
* Fix Reference on QR-invoice which was subscription number instead of QRR
* Move QR code logic for report on invoice instead of res.partner.bank
* Change addresses to "K", combined, in order to not have to split the building number from the addresses
* Upgrade QR-Invoice to 0200

reminder: *to activate Swiss QR-code add the system parameter* **l10n_ch.print_qrcode**

## Current behaviour before PR:

The version was still version 1.
The reference used was a the subscription number (previously badly named ISR reference on the bank).

## Desired behaviour after PR is merged:

Version 2 of QR-Invoice specs.

The reference on the invoice QR must be a Payment Reference in our case the ISR reference which is computed on the invoice (`l10n_ch_isr_number`)

### Current output with fixed reference

To be done later, add the optional bill information from Swico standards.


Be able to print a QR code with the ISR reference of the invoice (account.move).
