Add the Lexi DB package, which wraps badger DB to provide a simplified API, to capture the sometimes tedious mechanics that we've repeated in various places, and to add utilities for indexing data for quick retrieval of filtered data.
This change is just the addition of the package. I will demonstrate it's use in tatanka separately.
I'll add some more testing, but feel free to review as is.
See this diff for an example of how it would replace the tx DB for Ethereum.
