Add an AMP payment protocol example

[Bosch-0]

Another invoice protocol we may want to have as an example on the site is using an AMP invoice. Below is an example of one I generated in Zeus.

What interests you about seeing this on the site?

In my view, the point of the campaign is trying to simplify things for the user. For the time being, that's BIP21 + BOLT11. In the future, maybe that's replaced with BIP21 + BOLT12. Adding a third format seems like it might from the simplicity.

Yeah true, the BOLT12 offer example does convey the interoperability so it may not be necessary. My main reason was to just give more exposure to AMP / not play favorites (not that we are but yeah).

AMP invoices are quite large too
