Add an example #[wasmtime] Rust macro (#283)

Browse Source 
This commit adds a `wasmtime-rust` crate to the `misc` folder next to
the previously added Python extension. The intention is that this
showcases loading a WebAssembly file natively in Rust and how with an
attribute macro it can feel lightweight in terms of boilerplate.

The macro itself is pretty non-featureful today beyond the bare bones to
get anything working, but there's all sorts of possibilities like
JIT-compiled entry stubs we could eventually do with all the type
information!

# `wasmtime-rust-macro`
This is the actual definition of the `#[wasmtime]` macro, but it's intended that
this crate isn't used directly but rather the `wasmtime-rust` crate is used
instead.
