Added additional support for retrieving the system key from an offline SYSTEM hive file. This is useful in cases where you want to perform offline NTDS.dit forensics / password dumps.
API provides two functions LoadHive and UnloadHive which load and unload the SYSTEM hive file.
Added -sf/--system-file parameter to specify offline SYSTEM hive file to perform offline NTDS.dit hash dump from another computer.
Added parsing options for SYSTEM file as well as logic to handle offline boot key retrieval.

Added offline SYSKEY extraction to support offline NTDS.dit parsing from another machine. This feature required adding an extra parameter (-sf/--system-file) which accepts a SYSTEM file as its argument. Also, changed all references to VirtualAlloc/Free to malloc/free to reduce memory consumption. VirtualAlloc allocates a minimum of 64kb. Most fields within the ldap* structure are only a few bytes long which means that the remaining space would be wasted. For large NTDS.dit files, the parser would fail when calling VirtualAlloc with an 'out of memory' error. This change fixes these issues.
