Rune balance and issuance CLI

[utxo-detective]

This PR adds a new subcommand ord runes. I used the cli to create a couple of runes on signet to start experimenting with the indexer. The transaction creation is very basic and should not be used on mainnet. I ran into problems using the transaction builder as it did not support arbitrary op_return scripts in the tx_out, so i kept it simple to avoid modifying any transaction building logic

command: ord runes

Usage: ord runes <COMMAND>

Commands:
  issue    Issue a rune
  balance  Get rune balance
  help     Print this message or the help of the given subcommand(s)

Options:
  -h, --help  Print help

command: ord runes issue

Issue a rune

Usage: ord runes issue --amount <AMOUNT> --name <NAME> --divisibility <DIVISIBILITY>

Options:
      --amount <AMOUNT>              Amount to cast

  -h, --help                         Print help

Thank you for the PR! Just FYI, we probably won't be able to get to this right away, since we're grappling with index performance issues for a bit.

Sorry to close this, but I finished the PR I opened on Oct 15, #2544. #2544 uses the fundrawtransaction interface to fund the transaction, so we don't need to perform manual utxo selection and signing, avoids spending runic UTXOs in send and inscribe, and adds a whole bunch of tests.
