Best compatible LSDJ version and known quirks

[Slangenmans]

First of all: Thank you for this tool! Very sad to discover this so late. This would've been great to enter demoscene competitions with LSDJ tracks.

I was wondering what the best version would be to use with lsdpack. 8.5.1 was the latest stable version around the time this repo had its last release. Would that be the advised version?

I also noticed that some pitch shifts in 5.x.x versions were handled a little differently by lsdpack. What are some of the things to keep in mind when wanting create a optimized track?
