dMagnetic: update to 0.23.

Provided by Thomas Dettbarn in PR 55359.

This release saw major improvements when playing the original games
from the MS DOS releases. The images packaged in there used a
slightly different format than the AMIGA versions, resulting in
muted colours when playing with the LOW ANSI output.

An alternative algorithm has been introduced, called -vmode low_ansi2,
resulting in much more colourful, nuanced pictures. Just have a
look yourself!
