Right now I'm keeping a frame index, which is constantly updated,
because that's all I need (mpg123 seeks only by frames, so mpg321 will
do the same.) The problem isn't really that I need to be able to create
a frame listing: I have at least a reasonably accurate one. I need to be
able to tell madlib to use the new buffer (i.e., the new starting point)
in the middle of decoding, instead of re-starting the decoding process,
and I can't figure out any way to do so.
