Attempt to fix bad bootsectors
...
Some (recent) ISO images have started having a zero byte as the first
byte of the MBR boot code embedded in the hard disk image.
When the original Lenovo ISO is booted, nobody has reported any issues,
however when a patched IMG file is created from that, it just hangs
- which does match with having bad bootcode data.
I was unable to reproduce the issue when running the images in qemu,
which is even more confusing.
Since every working image has the same first byte (a "CLI" instruction)
we attempt to repair things by simply changing it back to that byte.

Add some guesses to FL2_copyIMG for older X200 extraction.
...
The FL2_copyIMG tool uses some heuristics to work out how to extract the
EC firmware image from inside the FL2 container. Many of these are simply
guesses, so there are checks to try to only match files that "look" right.
Add some matches for the 7XHT21WW and 7XHT22WW firmware (See #104 )

Remove most of the variables from the autoexec.bat template
...
Instead use a *.report file for each component and add data as we
go, culminating in the built image simply catting the report to the
screen to show the user what is about to occur.
This is on the path towards removing all variables from the autoexec
template - which would make it simpler to reuse the same template for
other commands (e.g the x200 series does not use dosflash.exe)
