Spina now provides exports for ESM modules and for CommonJS modules,

making it easier to consume in projects.
The ESM modules export all the Spina exports along with a "Spina"

default export that encompasses everything as a top-level namespace.
The CommonJS modules behave as normal, since one is expected to do

const Spina = require('@beanbag/spina');.
Notably, we are not setting "type": "module" in package.json, as our

main export is a UMD module and not a ESM module. This is important for

consumption in browsers, and also for compilation/unit testing in

general (setting it to "module" breaks all sorts of things).
There's also a fix that was found in the process where tsc wasn't

getting run correctly. Once fixed, it found a missing type import,

which has been addressed.

Successfully built and consumed Spina.
