refactor(op): Better naming + removed collection init

- added `Op.invoke(Monop)` and `Op.enqueue(Monop)`
- added `Operation.enqueue(Monop)`
- added `Monop.get(String)`

BREAKING-CHANGE:
- renamed `Monop.invoke(...)` to `Monop.enqueue(...)`
- removed `MonopCollection.init(...)` and `MonopCollection.initOnce(...)`
- renamed `Op.invoke()` to `Op.createOperation()`
- Bultin Ops and Operations `collection` field type changed from `MonopCollection` to `String`
