* Debounce the `onAddrChange` event handler when sending to a LN Address,
so we more accurately display the input form for LUD-12 and LUD-18 options
* Remove explicit URI encoding of Payer Data when sending to a LN Addr, since we're getting encoding for free via URLSearchParams
* Append `@stacker.news` to identifier values sent in payer data
* Don't do extra decoding when receiving LUD-18 data
