feat(core): switch database to Redb

[jrchatruc]

Motivation

Description

Closes #738

[fmoletta]

We shouldn't have code necessary for the redb impl in a module gated behind the libmdbx feature, maybe we could move ChainDataIndex outside this module ( to engine or engine/utils) and only keep implementation-specific code here

[jrchatruc]

Agreed, I moved the ChainDataIndex enum to its own utils module under engines here dbf7bdd

[fmoletta]

In the storage module we have tests that run the full test suite against the different engine implementations, we should add one for redb too. We just need to add this test:

#[test]
    fn test_redb_store() {
        test_store_suite(EngineType::Redb);
    }

Nice!, added the test here 404f388
