Subject: [PATCH] Fix Rust custom relay example

RelayMode::Custom takes a RelayMap, not a Vec<RelayUrl>, so the
previous example did not compile. Also fix the RelayUrl import path
(crate root, there is no iroh::relay module) and pass the now-required
preset to Endpoint::builder. Verified with cargo check against
iroh 1.0.0-rc.1.

Fixes #53
