coin_processor optimization: compile regex once

[keyliaran]

Currently, the regular expression is compiled anew with each iteration of the loop. This compilation process is resource-intensive, and there's no built-in caching mechanism. Consider utilizing lazy_static to cache the compiled result for optimization.

Currently, there are no unit tests for the indexer. I've conducted tests by running both the old and new versions on the same batch of events and confirmed that the resulting databases are identical.

Hey thanks for the PR! Could you use once_cell::Lazy instead? I believe it is recommended these days over lazy_static, better API / types rather than macro magic.

Done

Great! It seems CoinBalance::from_write_resource consumes 5x less CPU with your change. Can you fix the lint and have your PR merged?
