build_op: rewrap az when outside specified limits

fix #90

[kmharrington]

Ok question about this setup. Do the sun-safety checks happen after this un-wrapping? Right now it looks like it's quietly over-riding the az_branch setting for the example below. I'm happy it's found a safe scan but the original az-branch thoughts were for dodging to one side of the sun or the other and I'm seeing "solve sun safe moves" in before the "unwrapping" log messages.

This rewrapping happens before actually solving for sun-safe moves, so I don't think it will cause new sun-safety problem.
