Update the underlying build systems

[woksin]

Summary

Reducing the development foot print by using a more streamlined and slim version of our @doluttle/typescript.build package. The only controversial thing here is targeting ES2017 instead of ES2015, I don't think that this change is strictly necessary in order for this PR to work, but most it will reduce the size of the output and all modern browsers should support it.
