Tide: Update staticfile.rs Example

[eignnx]

I'm interested in using tide, but I kinda really need to be able to serve static files. The archived example was great, but it's now outdated and doesn't compile. Could we work on updating this?

Thanks!

I did a rough translation of the old example here, though I'm not sure it's in good enough shape to paste directly in.

@eignnx I'm thinking we should probably expose APIs for static file serving directly; I was never too happy with the old example, and it felt like something we should be providing a workflow for.

Ideas / constraints on what we'd like to handle would be very welcome!

In case anyone else comes across this issue thread, I've released my example implementation as a crate here: tide-naive-static-files. While this issue is being worked on, you may find it useful.

I was the author of the old staticfile example. I finally got some time to update staticfile code in my server, which maybe useful for @eignnx or anyone else.
