Description

This is part of #552 but it does not close it.

This stuff will likely move to the signer crate, just not right in this PR.

Changes

• Make sure sbtc crate integration tests are run in CI.
• Use bitcoin-core v25 in CI.
• Add a function to the BitcoinCoreClient for fetching transaction data that includes the transaction's fee. This new function, get_tx_info uses bitcoin-core's getrawtransaction RPC with a verbosity of 2, which is available in v25 and later.
• Remove the in_active_chain field from the GetTxResponse struct. It was only ever populated when the BlockHash was given as input, and we have another function that is better now.
• Add functions that apportioning the bitcoin fee for a deposit or withdrawal request after it has been confirmed. It follows [Feature]: Charge fees based on size #182, except it uses weight instead of size.

Testing Information

This PR adds an integration test for the new bitcoin-core client method and unit tests for the functions that apportion request fees. It also ensures integration tests in the sbtc crate get run.
