    opusdec: Fix PLC frame size calculations

    Previously, PLC frames always had a length of 120ms, which caused audio
    quality degradation and synchronization errors. Fix this by calculating an
    appropriate length for the PLC frame.

    The length must be a multiple of 2.5ms. Calculate a multiple of 2.5ms that
    is nearest to the current PLC length. Any leftover PLC length that didn't
    make it into this frame is accumulated for the next PLC frame.
