Transaction filter

[notJoon]

Description

Created a transaction filter. The structure is largely similar to a block filter since it was referenced, but it is designed to enable search for each data using TxResult.

Additionally, I utilized the method chaining to implement a query-like search. This allows the application of complex filtering criteria in a simplified manner.

Example Usage

filteredTxResults := NewTxFilter().
    Height(100).
    GasUsed(500, 1000).
    Apply()

f.ClearConditions()

Hey @notJoon,

Thank you for the PR 🙏

I apologize for the late reply on this, it slipped through my notifications.
I'll take a look at the PR soon and give feedback, I have a feeling we can improve it just by skimming through

I think we can avoid applying filters with elements on memory and do it directly using pebbleDB and their properties to iterate through keys in order.

Have a look at #12 . This approach can evolve even more adding secondary indexes. Not needed right now because queries take less than 20ms.

yeah, I think that would be much efficient than this filtering things.

Thank you for the contribution 🙏

Even though this PR doesn't contain connecting logic with the RPC layer, I see it as a good foundation for v1 of transaction filtering.

I've left some comments that should be addressed, I think we can greatly simplify the code

Looks good 💯

Thank you for addressing the comments 🙏

I've left a few suggestions, otherwise it looks good to go

I apologize for the late reply. I should be able to get it all done by in this weekend.

I'll open up a PR with @ajnavarro to connect this out with the RPC layer

Thank you for resolving the convos 🙏
