Image loading and saving

This release updates the way to save or load supported file format (tiff, jpeg, png, …) from/to corresponding iDRS objects CImage and CPage.

Instead of being exposed directly in the concerned objects, the two capabilities are brought together in a new CImageIO class, and are available via several methods: LoadImage, SaveImage, LoadPage, and SavePage.

This change has several benefits:

Load/Save options now only need to be defined once in the CImageIO class, instead of needing them as an argument for each call to CImage/CPage Load/Save; because this new class stores an instance of CImageLoadOptions / CImageSaveOptions (or subclasses) for each supported file format.
As a result of this change, the PageIndex property of the load option is moved out of relevant classes (CImageLoadOptionsTiff and CImageLoadOptionsPdf) and kept only as an argument of LoadImage and LoadPage methods.
It is no longer needed to know in advance the type of file to be loaded to provide the appriopriate CImageLoadOptions subclass.
In the future, this new class will enable us to offer more facilitators, such as a method to load a multipage file into a CImage or CPage array in a single call.

In addition, the CImageOptions class and its subclasses have been renamed to CImageSaveOptions[Xxx] to clarify their scope.

Note that the next release will contain further changes to the image option classes.
