Support building with OpenEXR 3.x

* Support OpenEXR 3.0

Try to find OpenEXR 3.0 using the upstream cmake config, and fallback to the previous algorithm if not found

* Add explicit ImfFrameBuffer.h include

This was transitively included with OpenEXR 2.x, but that's no longer the case with OpenEXR 3.x
