1c7f95c0 - Use TypeScript source for development, swap to build during release

Use TypeScript source for development, swap to build during release This changes the JS SDK to point `main` to TypeScript source and remove any indication of `typings`. For local development and CI workflows, it means many steps can run without building first, which saves lots of time. During release, we still build for Node and browsers as before. The release script adjusts the `main` and `typings` fields before publishing and distribution to point to the built output for those that use them.
