[MERGED PR] Cyborg movement speed rebalance

[Ikea]

So Cyborg Treads are now slower.
For humans too?

How can humans use Cyborg Treads more effectively than cyborgs?

Should we nerf humans with treads too, so their speed matches light w/ treads?
Then they are slower than without treads - and no human would want to get treads.

This pr only effects cyborg values and human values are outside of the scope. Technically this pr does not change tread values, it just makes other parts values better/worse. Either way treads on humans represent different balance concerns and have very little overlap so I see no need for them to be tied together.
