Update TypeScript to support selecting different builds

[awonak]

I have a project where I compile my binary with several different sets of build flags to support different firmware features (like reversed encoder or flipped OLED). It would be helpful if the TypeScript library supported serving different binaries based on user interface selections.

See "use as node module" it's actually for the browser
