manual `long.js` dependency

[goertzenator]

Can the manual dependency on long.js be eliminated? I've got a spago setup that gets converted to a nix build and it is not clear to me how I would go about injecting a non-purescript dependency.

Can a pre-built long.js just be added to the source of this project?

The https://pursuit.purescript.org/packages/purescript-int64 package is basically exactly what you suggested: this package, but with the long.js dependency inlined.
