* Added proper metadata reading from multigame carts.
* Added gamecard -> NSP dump option:
* * Compatible with file splitting (for FAT32 support). The same layout from splitNSP.py is used: a directory with numbered part files (00, 01, etc.). The archive bit is enabled right away in this directory to allow HOS to treat it as if it were a whole file. This way, it can be used with any application with NSP-handling capabilities.
* * Compatible with CRC32 checksum calculation. Disclaimer: NSP dumps can't be verified against the XML database.
* * Output NSPs contain a metadata XML file based on the information from the CNMT NCA for the application, which is decrypted using code from hactool. The necessary keyset is loaded from "sdmc:/switch/prod.keys", which can be generated using Lockpick.
* * If a multigame cart is used, you'll be able to choose which application to dump from the menu.
* Dump verification process tweaked for multigame carts: it'll now look for a possible checksum match using the Title IDs from all bundled applications.
* Improved error reporting in dumper.c when a write operation fails. Furthermore, if a write error is produced when trying to write data to an offset past the FAT32 file size limit (0xFFFFFFFF bytes), the application will suggest the user to enable the file splitting option.
* Tweaked part sizes for splitted dumps: XCI/raw partition/manual file dump part size now matches the one used by XCI-Cutter, while the NSP part size matches the one used by splitNSP.py.
* Minor fixes to the UI code.
