Allow usage of FatFS simple gpt parsing for setting the fat partition in case its label is not hos_data.
Additionally allow hos_data partition to not be the first one.
An edge was fixed where the checks for if it's possible to backup files for partition manager would overflow and end up with a value < 1GB and thus proceeding to the backup/restore process.
Allow you to select up to 2 emuMMC + Linux + Android.
Any combo is allowed, even if you just want to repartition it back to one FAT partition.
The procedure is automatic on selecting sizes and offsets.
The tool is also able to backup your SD Card into Ramdisk and then get restored, if the total used size is less than 1GB.
If you have more files than that, you will be asked to copy your files to your PC via UMS.
It also allows you to flash L4T Linux images and Android Twrp images.
The Flash Android can be also used to reboot into Twrp if a file to flash is not found.
