this allows us to reuse the code in wiggle-generate elsewhere, because a proc-macro=true lib can only export a #[proc_macro] and not ordinary functions. In lucet, I will depend on wiggle-generate to define a proc macro that glues wiggle to the specifics of the runtime.
wiggle
An experimental implementation of bytecodealliance/wig crate which
generates Rust bindings from *.witx that are meant to be more idiomatic
and hopefully allowing for easier polyfilling between different WASI
snapshot versions in the future.
