Gets util working again.
Handles being unable to multilaterate a single aligned event.
Adds readme message with piping example.
Renames event generation to zero detection.
Adds max delay estimation.
Adds units to constants.
Makes multilateration handle degeneracies slightly faster.
Does dropped event detection in alignment. Multilateration doesn't support this output yet, though.
Converts to struct packing for piping.
