[Feature Request] Extractors of different speeds

[davqvist]

Hi, I am working on a modpack right now and want to include your mod into the pack.
Loving it so far, fits exactly for what I need.

One thing I am missing though, if there were Extractors of different speeds to match the conveyor of different speeds, so 3-4 different variations, at best with the extraction rate speed configurable, this would be perfect. Would you consider adding something like that?
