* feat(sqlite): parameterized prep statement exec
- from nim-eth
* feat(store): sql-only-store
- add getPage(...) to sql-message-store
- acts as separate store impl that can be activated with
`--sqlite-store=true`
* test(store): new test-suite for sql message store
* test(store): waku_store test SQL-store compatible
* perf(store): avoid builing an additional B-tree in sql query
- use `receiverTime` as the last ORDER BY column to fully utilize the
primary key sorting
feat(store): retention time
- retention time in seconds can be specified via `--sqlite-retention-time=`
