- thanks to NVAR extended headers, item tails are back
- fixed a bug with "Extract uncompressed" producing incorrect results
for multiple sections
- fixed detection and parsing of NVRAM external defaults file
- fixed "Extract as is" on NVAR entries not including extended header
- small bugfixes and refactorings
