Rust 101 - 13: Type Parameters and Associated Types

Following on from [video 12](https://diode.zone/w/9Db2EwKP8ga6A5oaBhripm), looking at how to add type information to traits, to make them flexible enough to describe generic code with different types, for example how to add a u32 to a u64 and return a u128, without defining a whole new trait for every combination of types.
