#1 Query language

Creates a query language instead of the [Filter](https://git.cesar.com.py/cesar/ledger-prototype/src/main/utxo/src/filter.rs#L78-L121) struct. Although the Filter is quite useful, [which is heavily inspired by Nostr's filter](https://github.com/nostr-protocol/nips/blob/master/01.md#communication-between-clients-and-relays) it falls short compared to SQL. This PR will introduce a query language, which aims to be a statement parser, compiler, and virtual machine.
