Fix engines i package.json

Fixed engines - node and npm - to be more lenient (>= instead of ~)

Split into two entrypoints

Due to an issue with Cypress and importing @angular/* dependencies I've decided to split the lib into two entrypoints; root (@colsen1991/ngx-translate-extract-marker) and /extras. The latter contains the new pipe and directive, as well as the module which includes both.

Fixed a few bugs

Fixed some errors related to changes in the build process

Initial release

Marker function, pipe and directive, including a NgModule with the latter two is now released
