Implement EMV QR Code v1.1 Specification

[AlexisDD]

Hi,

The documentation mentions compatibility with v1.1 of the EMV QR Code Specification. However, it seems that the library uses the v1.0 Specification from 2017 (in the docs folder), leading to the absence of certain features.

For example, I need to use new fields that were added in v1.1 in the Additional Data Field Template (ID "62") and are not implemented in the library :
- Merchant Tax Id (ID "10")
- Merchant Channel (ID "11")

As a workaround, I've incorporated these fields into the "RFU for EMVCo," enabling the use of IDs 10 and 11 but it would nice to update the library to accommodate the new specification. I've only noticed this particular example so I didn't check whether v1.1 is partially supported or not supported at all.
