storage request: absurd-sql

[gitmalong]

absurd-sql uses sqlite3 on top of indexeddb with excellent benchmarks as it treats IndexedDB like a disk and stores data in blocks there.

It would be better to consider sqlite3 storage rather than absurd-sql because GlueSQL can already replace the IndexedDB backend of absurd-sql
