Use microbundle instead of TSC

Seems to be a great tech option which allows for easier use of multiple export types

• amd – Asynchronous Module Definition, used with module loaders like RequireJS
• cjs – CommonJS, suitable for Node and other bundlers (alias: commonjs)
• es – Keep the bundle as an ES module file, suitable for other bundlers and inclusion as a <script type=module> tag in modern browsers (alias: esm, module)
• iife – A self-executing function, suitable for inclusion as a <script> tag. (If you want to create a bundle for your application, you probably want to use this.). "iife" stands for "immediately-invoked Function Expression"
• umd – Universal Module Definition, works as amd, cjs and iife all in one
• system – Native format of the SystemJS loader (alias: systemjs)
