Building on the previous commit to invoke not invoke `npm install` this takes
the commit a step further (to hopefully fix some races) to use Webpack's native
bundled wasm support.
It turns out the circular dependencies between the wasm module and the module
using it wasn't quite working out so a number of imports had to be tweaked, but
otherwise it's a nice transition where we don't have to base64 encode anything
in tests any more!
This'll match more closely what wasm eventually does natively, which is
importing these functions directly and not allowing changing them over time.
Closes#25
This commit migrates from `wasm_bindgen!`-the-macro to
`#[wasm_bindgen]`-the-attribute. The actual mechanics of the macro are
relatively simple in just generating some shims here and there, but wrapping
everything in one huge macro invocation can often seem intimidating as it gives
off this feeling of "oh dear anything can happen here!" Using an attribute
should curb expectations much more greatly of "oh there's just some extra stuff
happening behind the scenes".
The usage is otherwise relatively straightforward and close to what it was
before, but check out the DESIGN.md/README.md changes for more info!
Push the compiler to do trait resolution to figure out what each type is bound
with in JS, and that way we can accept effectively all types (so long as they
implement a trait).
