This will find kerning groups with known prefixes.
In some cases not all kerning groups will be referenced
by the kerning pairs. The algorithm for locating groups
in convertUFO1OrUFO2KerningToUFO3Kerning will miss these
unreferenced groups. By scanning for known prefixes
this function will catch all of the prefixed groups.
These are the prefixes and sides that are handled:
@MMK_L_ - side 1
@MMK_R_ - side 2
