* Thread-safe.
* Provides getter/setter functions for the data types used by nxdumptool's configuration.
* Each setter function writes the modified JSON configuration back to the SD card.
* Configuration is validated on interface initialization. If validation fails, a default JSON template is loaded from the application's RomFS and written back to the SD card.
Other changes:
* Implement directory creation.
* Moved more preprocessor definitions to defines.h.
* Replaced strtok() calls throughout the code with strtok_r() to guarantee thread-safety.
* Both gamecard header and decrypted CardInfo area are now retrieved upon gamecard insertion. LAFW version is checked against the CardInfo LAFW version right afterwards.
* Expanded GameCardStatus enum to add NoGameCardPatchEnabled and LotusAsicFirmwareUpdateRequired values.
* Updated utilsReplaceIllegalCharacters() to perform replacements on a per-codepoint basis, which means that invalid multibyte UTF-8 codepoints can now be replaced with a single ASCII underscore.
* Updated utilsGeneratePath() to truncate path elements that exceed 255 UTF-8 codepoints (safe limit for FAT and NTFS filesystems).
* Heavily simplified core logic in title functions by using newly defined TitleStorage elements (which hold the NCM database/storage handles, a TitleInfo array and a title counter) instead of the old, global index-based methods.
* Simplified background gamecard title thread logic by always returning duplicated TitleInfo data to the user.
* Update title API to account for the previously mentioned changes, including functions to free duplicated title data.
* Fallback gamecard filename string now also holds the gamecard package ID whenever possible.
* Implemented HDCP patching for Control NCAs.
