LUD-19: Pay link discoverable from withdraw link.

author: akumaigorodski discussion: https://t.me/lnurl/12568

Merging "pay" and "withdraw" related to a same SERVICE in a WALLET

LNURL-withdraw may contain a payLink in its JSON response. This is done to recognize a fact that SERVICE may want to allow both deposits and withdrawals to user account and as such make a static payment link easily discoverable from withdraw link.

When WALLET sees this it may store and show a compound item to user which would allow to both deposit and withdraw (and also to show an up-to-date SERVICE balance if LNURL-withdraw contains a balanceCheck field).

Modification required in SERVICE callback JSON of LNURL-withdraw:

 {
   tag: "withdrawRequest",
   callback: String,
   k1: String,
   defaultDescription: String,
   minWithdrawable: Integer,
   maxWithdrawable: Integer,
   balanceCheck: String,
+  payLink: String,
 }

payLink is raw URL (not bech32-encoded).
