[Enchancement] : Support caddy server

[baseplate-admin]

Hi there,

Thanks for making this awesome project. Do you guys plan to have support for caddyserver?

Here is a simple config to have caddy support X-Sendfile :

   handle /* {
        reverse_proxy localhost:8000 {
            @sendfile header X-Sendfile *
            handle_response @sendfile {
                rewrite {http.reverse_proxy.header.X-Sendfile}
                file_server
            }
        }
    }

If caddy supports X-Sendfile then it should be good to go already.

Caddy by default doesn't have X-Sendfile directive.

From their document they use X-Accel-Redirect

reverse_proxy localhost:8080 {
	@accel header X-Accel-Redirect *
	handle_response @accel {
		root    * /path/to/private/files
		rewrite * {rp.header.X-Accel-Redirect}
		file_server
	}
}

Shouldn't there be a section in documentation clarifying this or how to set up caddyserver?
