Ability to serve embed.FS files

[night-codes]

Will there be a native fasthttp way (like .ServeFile) to share filesystems of embedded files, support for which came in go 1.16?

A pull request for that would be very welcome. Maybe add a FS fs.FS member to fasthttp.FS and if it's not nil use FS.open instead of os.Open.

@erikdubbelboer with that solution, how might it handle mustCompress? Or just not support it for embedded content?

[erikdubbelboer]

Yeah I guess that's not supported then.

I'm willing to try this feature, my basic thought is to add a interface like

StaticFSHandler(prePath string, staticFS fs.FS) RequestHandler

and modify fasthttp.FS as talked above
