TODO:
- Merge duplicated regions
There can be multiple L2 directory tables, for A/B recovery or
to support different SoC SKUs. They point to the same regions,
causing the same area to be shown multiple times in the parsed
image.
- Better quirks support
PSP hardcodes certain sizes and address types for some files.
The parser might thus fail, even though it works on real hardware.

As the first step towards automated parsing, this change set replaces outdated BootGuard-related parsers with shiny new KaitaiStruct-based ones.
It also does the following:
- improves Intel FIT definitions by using the relevant specification
- adds sha1, sha384, sha512 and sm3 digest implementations
- updates LZMA SDK to v22.01
- moves GUIDs out of include files to prevent multiple instantiations
- enforces C++11
- adds Kaitai-based parsers for Intel FIT, BootGuard v1 and BootGuard v2 structures
- makes many small refactorings here, there and everywhere
+ FFSv3 support with large files and large sections
+ proper names for Flash Descriptor v2 regions (#89)
+ better alignment calculations (#96)
+ improved NVRAM parser
+ post IBB hash support for Boot Guard
+ bugfixes
+ companion tool updated
- human readable JEDEC ID
- NVRAM parser separated from FFS parser
- added support for LZMAF86 sections
- solved a bug with parsing of VSS variables with invalid sizes
- added wrappers over Qt classes for seamless replacement if Qt is not available
- added bstrlib as submodule
- only UEFIExtract works with this changes for now, others will followa bit later
- added support for all Phoenix SCT stuff from NVRAM volume: Intel
microcodes, CMDB block, SLIC pubkey/marker.
- added support for EVSA extended variables (bigger than 0xFFFF)
- better EVSA parsing (invalid data vars are shown now)
- FlashMap entries now have human-readable types
- various small fixes and refactorings
Thanks to lordkag for #41:
- improved parsing of Intel flash descriptor
- improved detection of Tiano/EFI 1.1 compression type
- added 2 UEFI capsule GUIDs used by Lenovo
- solved potential crash on very low memory available
- UEFIExtract and UEFIFind update to include the latest parser changes
- nothing major, just reworks and preparations for the new rebuild code
- added try / catch bad_alloc to prevent crashes during decompression of
malformed Tiano/EFI11 compressed data
- files split into common and app-specific ones
- messages from parser and finder separated
- ffsEngine split into multiple classes to reduce complexity
- still no image rebuild
