More benchmarks on heatshrink vs lzexedat

I ran some more meaningful tests comparing the heatshrink and lzexedat depackers. All of these tests are on the amd64 server without KVM. The help and ELD depack tests are with the inline literal store optimisation enabled, apparently speeding up the runs by about 10%, for both heatshrink and lzexedat.

LZEXE data compression format

Yesterday I added the LZEXEDAT compression method to inicomp. This currently uses a plain LZEXE format data stream, without any Meta data.

The compression is done by lzexedat.exe, a DOS tool that generates the headerless compressed stream. I added the lzexedat.sh script which deals with leading dotdots then calls dosemu2. (The redirected drive does not allow to use a dotdot to go beyond its root directory, so the script will change the directory of the dosemu2 drive and strip the leading dotdots.)
