AUDIO: (FM-TOWNS) - replace fixed hanging notes buffer with a dynamic chain

(This works around issues with some Indy 3 sound tracks. These tracks seem to be broken, since they have way too long duration values for some notes which would fill up the event buffer rather quickly. I tested with the UNZ emulator to be sure that this is an issue which also occurs with the original driver.)
