OLAF wakes give a "Tower Strike" warning if they enter the tower with tower shadow enabled #3441

Description

@andrew-platt

Bug description
This warning is mostly inconsequential, but it is very misleading.

This was discovered with an AeroDyn driver case, which is a rigid structure. With tower shadow turned on, the blades and tower are rigid, so a tower strike should not be possible with a properly configured turbine. However, the call sequence SetInputsForFVW -> TwrInflArray -> getLocalTowerProps will trigger this warning when any wake points are inside the tower (occasionally could happen due to numerics). The warning is then printed indicating it was a blade that hit the tower when in reality it have only been a small numerical artifact pushing the wake point into the tower.

To Reproduce
May be difficult to reproduce.

Suggested fix
Add a flag from FVW passed optionally through the call sequence that disables that warning.
