use keysets with hex ids when creating proofs to send

[elnosh]

some mints still have non-hex keyset ids. Example minibits mint has keysets:

"keysets": [
  {
    "id": "9mlfd5vCzgGl",
    "unit": "sat",
    "active": true
  },
  {
    "id": "00500550f0494146",
    "unit": "sat",
    "active": true
  }

when creating proofs to send, it generated proofs like such:

"proofs": [
  {
    "amount": 1,
    "secret": "60822b310d5a197d370dcf9948a1cff2b8fd95846d3c55fde2992e3da96d3290",
    "C": "03bea6d0cc5a1d83cced22b3ac00585101d756d0ffaef59642a3904efb046f7cd1",
    "reserved": true,
    "id": "9mlfd5vCzgGl"
  },
 ...
],
"mint": "https://mint.minibits.cash/Bitcoin"

using keyset id 9mlfd5vCzgGl instead of using the hex keyset id 00500550f0494146

Is this still an open issue? I seem not to have any issues when using that particular mint.

just tried it and yeah it's using the hex keyset id now
