* fix bug in nand.bin class: when creating a new nand.bin, initialize fst_pos in fst entries

* insert new entries in nand.bin at the start of the chain instead of at the end ( to closer mimic IOS FS behavior )
* oneswanzenegger: create /sys/cert.sys when creating a new nand.bin

this is a tool to list saves in an extracted nand dump
this is a tool to list/extract/delete saves to/from an extracted nand dump. saves are extracted, packed into a data.bin, zipped up with a txt file
that says a bit about the save, and then stored in a folder. you must designate a folder and provide the necessary keys before extracting saves
will work. i chose to go with data.bin as it is a way to store the entire save in 1 file and also allow the save to be installed using the
system menu. and i went with the zip format 1) to save space, and 2) to keep a save and the description all in 1 compact file.
saves are extracted to "<the folder you specify>/<TID upper>/<TID lower>/#.zip". the # is chosen by the lowest available number starting with 1.
there is no need for the saves to be in numerical order, if you have 10 zips for the same game and you decide to delete "3.zip", it will cause
no issues, and next time you extract a save for this game, it will use the filename "3.zip".
TODO:
add some sort of extract/delete/install functionality
installing saves back to sneek nand still isnt done
