Add options to use OPFS

[Ranjith-KumarT-IBM]

Hi there,

Thanks for this awesome project!

I would like to know if it is possible to add options to use OPFS, it quite new but most browser as of now supports opfs.

why do we need opfs ?
There are few niche cases where native fs would be far better and resilient than indexed DB like video streaming and recording.
