* Added a function to write re-encrypted NCA and/or FS section headers. Getting ready to re-implement NSP dumping.
* Added more CNMT XML fields (thanks 0Liam).
* Updated my to-do list because I'm dummy.
* Added 'encrypted_header' members to both NcaContext and NcaFsSectionContext. In-place re-encryption isn't desirable in this case.
* Fixed FsAccessControl-related type naming for ACI0 blocks.
From now on, I'll delete code from the legacy codebase directory as soon as specific features from it are rewritten... Because it's a mess to navigate.
