Output descriptor with both receiving and change paths about descriptors HOT 4 OPEN

Oh okay, it is not directly in the specs but seems like an extension. Would be cool to have this anyway though!

I believe this format is specific to Ledger. It's a more compact way to represent internal/external keys, making them easier to display on the device. @bigspider may have more insight into this, especially if it has gained wider adoption.

By the way, this library supports Ledger HWW. You can use standard * descriptors, and they are automatically converted to the Ledger format for use on Ledger devices.

The multipath syntax is not (yet?) a standard (albeit already quite widely adopted by many software wallets, I think). There's a PR to add it to descriptors: bitcoin/bitcoin#22838

Ledger's script wallet accounts are based on the wallet policies BIP proposal, also adopted in BitBox02 and Jade, but not yet standardized either.

Yeah, I asked this because I was using an output descriptor from Sparrow for my tests and it is using this multipath syntax.

@landabaso Do you think it would be appropriate to support this syntax in the library, considering its growing adoption?
