Add an example to load file from a directory along with https://remix-ide.readthedocs.io/en/latest/locations.html#load-one-of-the-default-remix-files

Hi,
Thank you for this package, it is very useful.
I found an issue while using it with AWS Cognito.

After a POST with status 302(redirect) in the OAuth2 flow, the redirect location url has the "state" parameter already decoded and will not match anymore the session state.

I think the correct fix is to encode/decode state when set-to/get-from URLSearchParams but not encode it in the sessio
