Feature Request : Native File System based Sqlite Database access support.

New Chrome 78 beta, has released the experimental feature of Native File System access directly. Even mozila firefox has been actively working to implement it. As of chromium Edge will inherently have it.
This will be a real boost to use case of this library,

I would like to request the feature to allow this script to access and modify data direct on disk.(once user give permission to select directory)

Start by reviewing how sql.js accesses SQLite in the browser and the Native File System access described in the issue. Define the permission and direct-on-disk behavior, then verify that the library can select a directory and read and modify a SQLite database there.
