XEX2 Loading Fixes (#51)

Browse Source 
* Fixes loading .xex import table names when a name is not aligned to 4
  bytes.
* Fixes loading .xex optional headers, adds missing case when the
  header_key & 0xFF == 1
* Fixes loading .xex base address and entry point to be the XEX2
  base/entry to successfully resolve all import thunks.
