Add Auto turrets to raven micro

**Is your feature request related to a problem? Please describe.**
Safe raven TvT bot opens up with raven and dies to marine pushe with the raven not using any energy.

**Describe the solution you'd like**
Use auto turrets on small scale fights. Unsure on how to look for turret placement positions.

**Additional context**
> generally 'when attacking: place them offensively (next to enemy tanks)' and 'when defending: place defensively in a retreating manner'
well at least for tvt
i dont think autoturrets are very good in the other matchups
there is also raven autoturret harass for killing workers
