Add magic routing hint support (#265)

Browse Source 
* Receive: Add magic routing hint support

* Send: add MRH support

* Filter out and reject self-transfers

* Extract self-transfer validation in own fn

* PrepareSendResponse: use onchain fee as fees_sat if MRH present

* Use onchain tx fee as payment fee, if MRH used for direct onchain tx

* Fix swap fee calculation when MRH is used

* Apply boltz-client patch that aborts send if tx broadcast fails

* Send with MRH: return pending payment

* Receive with MRH: validate BIP21 amount, address

* Emit remaining events for MRH Send, Receive

* Sync: update swap info and emit events after new tx data is persisted

* Extract MRH send into its own send_payment_via_mrh()

* Pending Send via swap: store tx fees for pseudo-tx

* Fix clippy
