Support for accessing files from local filesystem with in html

[shareejvk]

As of now, I am not able to access files from the local file system within HTML.
Reading files as binary then converting to base64 cant be considered as a solution to this issue as this is super slow especially for video files.
I believe local file system access within the renderer is a very basic requirement.

One should be able to do something like:

<video controls src="file:///User/dave/film.mp4" />

I updated the custom protocol example in tauri-apps/wry#315 which should make it more like a real life sample to load local assets.
@lucasfernog @lemarier Does tauri support this feature yet?

Btw, I tested file:// protocol last weekemd.
It can be used to load the webview by with_url.
But it is extreme restricted in the HTML files on all platforms.
And even there are some hacks and workarounds. It still has some wierd behaviors.
