Software using LibHac

hactoolnet - A hactool-like program for dumping common Switch file formats

Change log:
- Add basic save file editing. Any files already in the save file can be written to
- Check validity of save files
- Check validity of PFS files
- Check validity of SwitchFS and SD cards
- Check file hashes in HFS archives
- Partial NSO support
- When keys required to decrypt an NCA are missing, throw an exception with information about the missing keys.
- Add more sanity checks when reading an NCA.
- Read only the NCA header when first opening an NCA. This allows for reading of partial NCAs and slightly improves performance when opening an NCA.
- Fix bug in CombinationStream when reading across boundaries
