RIFF Box update: Samsung J250F 7.1.1 supported

reworked the Error Handling mechanics in ISP eMMC reading code.
Now errors are handled in smart way, when read errors happen, plugin automatically re-reads erroneous address as many times as needed until the read happens without errors
This greatly increases plugin ISP read stability, and allows working even with very poor quality of ISP connection;
the counter of I/O read errors happened during operation is added to the plugin main window status bar.
added Backup partitions feature: For this, select needed partitions, right-click with mouse, and choose ‘Backup partitions’.
This will extract current data from partitions and store contents into single file.
This backup can be restored later with ‘Load Backup File…’ right-click feature.
added ‘Used Size’ column into the parsed partitions list window
partitions extraction (like save Partition, save Selected Partitions, etc) algorythm is changed: now are to be saved only used part
of partition (specified by used size), the remaining of allocated partition bytes are not saved.
added UFS-based devices support for Repair Packages
interface skin is updated
some other fixes applied.
