🚀 [Feature]: fiber/middleware/filesystem - support for templating

Feature Description

I am embedding a html file using the filesystem middleware.

There is currently no support to add some templating.
It would be good to inject some simple variables into the html file.

what about this https://github.com/gofiber/template/tree/master/html#example-with-embedfs ?

[pjebs]

It does not provide the full options and configurability of the filesystem middleware.

Eg directory listing

Why to want filesystem middleware for templating? It's just for serving files

[pjebs]

The files I want to serve are mostly html files with some placeholders inside for a templating engine to substitute.
