fix: stop using "magic" numbers in string operations for the copyannofile2log feature fix: When using the copylogfromannofile workaround, extract the build ID and build duration and add to the log as these are useful for analysis. The log should now be identical to the stdout file. fix: Remove extra blank lines from output in copylogfromannofile mode.

Usage:
  addextension  <kernelRom> <extensionRom> [<outputfile>]

If <extensionRom> doesn\'t exist, addextension will try concatenating
the <kernelrom> and <extensionrom> names.
If no <outputfile> is specified, the default is sys\$rom.bin
