feat: drop direct babel dependency + allowing dynamicImport, objectRestSpread (#12)

* update babel version

* update babel in getReplacement, replace and README

* format as json

* use babel object supplied by plugin api for everything but register

* .eslintcache really wants to belong to the codebase

* implement @mlrawlings poc, remove dep for babel/core, /register

* fix typos

* added myself to the contributers

* bump babel plugin macros version again

* pass parserOpts to template fn

* added some test to assure correct behaviour of parserOpts

* pass plugins and presets to child transforms

* trust parent babel to pass the correct parserOpts, including plugins

* codeToAst does not need to be a func anymore
(it screws with test coverage somehow)

* update readme to reflect changes

* fix formatting for md files

BREAKING CHANGE: We are inheriting the babel configurations of the main babel-process, instead of starting a new one. Thus we're not reading the .babelrc.
