Handle values not in TWFix32

[Eugene Wang]

For extension method that should get values in TWFix32 like DPI, sometimes it's uint instead. Make it handle the conversion in that case so it doesn't throw exceptions.

Hi Eugene,

Is there an ETA on this issue? I upgraded NTwain and I'm getting exceptions due to this.

Fixed #5 for TWFix32 conversion exception in extension method.
