* \brief IconImageFilter
* \details This filter will extract icons from a File
* This filter will loop over all known sequence (public and private) that may
* contains an IconImage and retrieve them. The filter will fails with a value
* of false if no icon can be found
* Since it handle both public and private icon type, one should not assume the
* icon is in uncompress form, some private vendor store private icon in
* JPEG8/JPEG12
*
* Implementation details:
* This filter supports the following Icons:
* - (0088,0200) Icon Image Sequence
* - (0009,10,GEIIS) GE IIS Thumbnail Sequence
* - (6003,10,GEMS_Ultrasound_ImageGroup_001) GEMS Image Thumbnail Sequence
* - (0055,30,VEPRO VIF 3.0 DATA) Icon Data
* - (0055,30,VEPRO VIM 5.0 DATA) ICONDATA2
*
* \warning the icon stored in those private attribute do not conform to
* definition of Icon Image Sequence (do not simply copy/paste). For example
* some private icon can be expressed as 12bits pixel, while the DICOM standard
* only allow 8bits icons.
*
