-/**
- * This object contains helpers buffering incoming data & deconstructing it
- * into parcels as well as buffering outgoing data & constructing parcels.
- * For that it maintains two buffers and corresponding uint8 views, indexes.
- *
- * The incoming buffer is a circular buffer where we store incoming data.
- * As soon as a complete parcel is received, it is processed right away, so
- * the buffer only needs to be large enough to hold one parcel.
- *
- * The outgoing buffer is to prepare outgoing parcels. The index is reset
- * every time a parcel is sent.
