Add embedding mode with arg flag. Currently working (#282)

* working but ugly

* add arg flag, not working on embedding mode

* typo

* Working! Thanks to @nullhook

* make params argument instead of hardcoded boolean. remove useless time check

* start doing the instructions but not finished. This probably doesnt compile

* Embeddings extraction support
