Initial casting implementation
Explicit casts can be performed with the syntax 'cast<type>(input)'
and implicit casts can be performed with the syntax 'cast(input)'
where the output type is determined by inference.
To prevent casting shenanigans we only allow casting of primitive
types and of types to themselves (essentially creating a copy).

- Reowolf's pseudo-socket API mimics the API of UDP sockets
- This example corresponds closely with that of the socket API, differing only in:
1. an added import of the pseudo-socket header file
2. (pseudo-)socket operations' identifiers are prefixed with `rw_` (short for "Reowolf").
