Convert Kshootmania chart into VOX version 12

KSH File format specification: https://github.com/m4saka/ksh/blob/master/ksh_format.md

Biggest difference between vox 10 and 12 is how the laser position is represented. Vox10 uses 0-127 int, in Vox12 it's float value, which is much more accurate and precise, and this also brings the ability to make 1/64 lasers(The chart system is revamped in the game).

By convert perfect curve, using the comment system in ksh editor, adding "cstart" to the beginning of the laser start, and adding "cend" at where you want to stop the curve processing.
