@aristidesstaffieri I think the content from this PR is great, but I noticed it's mostly exploring only the part of parsing a given existing string to a Sep7Pay or Sep7Tx object.

There is this other positive aspect of the SDK which is creating those Sep7 objects using the existing getters and setters of the Sep7 class, so devs don't need to worry about decoding/encoding stuff. Like the below:

    const uri = Sep7Tx.forTransaction(tx);
    uri.callback = "https://example.com/callback";
    uri.msg = "here goes a message";
    uri.toString(); // encodes everything and converts to a uri string

    const uri = Sep7Pay.forDestination("G...");
    uri.callback = "https://example.com/callback";
    uri.msg = "here goes a message";
    uri.assetCode = "USDC";
    uri.assetIssuer = "G...";
    uri.amount = "10";
    uri.toString(); // encodes everything and converts to a uri string

There is also the addSignature and verifySignature functions which would be nice to highlight! :)

What do you think?

Yeah totally, I could expand on using a few setters for each operation. I'll show the signature helpers as well. 👍
