>StaticQueue: LinearisedIterator

Using C++ iterator interface to fix the main problem of a standard ring buffer of non-contiguous regions is a cute idea, but I like to use a "bip buffer"[1] instead which actually always gives you real contiguous regions so you can pass the pointers to things like a dma engine.

The tradeoff is that you have in the worse case only half the buffer available - the ring buffer essentially becomes a kind of double buffer where you periodically switch between writing/reading at the end or the beginning of the storage.
