- 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
