Subject: [PATCH] (fix): revert #130's breaking change of tsconfig options
 (#415)

- not sure why this change was made in that PR as it was unrelated to
  the rest, but it broke some things related to Babel usage and maybe
  other things
  - e.g. babel macros were not included per #413
  - and it used `tslib` instead of adding babel helper functions

- add a comment of why it seems like the target is overriden to esnext
  - though I am not sure of the original reasoning, as it has existed
    since very early versions of TSDX, see #130 comments
