Vff reader might be unreasonable restrictive

[cpinter]

When attempting to load a .vff file, Slicer reports the following errors:

• [ ] The value entered for the rank must be 3.
• [x] The values for the origin must each be greater than or equal to 0.
• [ ] The value entered for the rawsize must be greater than or equal to 0.
• [ ] A string was not entered for Handle Scatter. The value must be separated from the parameter with an '='. The value entered for Handle Scatter must be factor.
• [ ] The value entered for the Reference Scatter Factor must be 1.
• [ ] The value entered for the Data Scatter Factor must be 1.
• [ ] A string was not entered for the filter. The value must be separated from the parameter with an '='. The value entered for the filter must be Ram-Lak.

However, I installed Microview and loaded them with no reported issues. I then exported them to DICOM and loaded that via Slicer successfully.

This would imply that the reported errors above are not errors but more warnings.

Commit 3fb93b870bf8f12cfb2b2e0062534e4045468253 relaxed the condition about the origin.
