Add a few sanity checks to the Convert Orientations filter

[imikejackson]

A very easy way to mess up in the filter is to accidentally select "Orientation Matrix" instead of Quaternions because they are both next to each other in the combo box. Maybe we should put in a small sanity check section that does something like:

If the destination selection is Anything OTHER Than Quaternions and the output array starts with "quat" then we should throw a preflight error or at least a very strong warning that the user has most likely selected something inconsistent in the UI.

Hi @imikejackson,

Most of the filters require orientations as either Euler angles or quaternions. Are there any filters that require the orientation matrix, or do users convert orientations to the "Orientation Matrix" for the sole purpose of writing/exporting? Maybe that would help this issue, to let users know that they have selected an orientation representation (e.g., orientation matrix, rodriques vectors, etc.) that is not required/used by any filters and are solely for the user's benefit outside of DREAM.3D. What do you think?
