Replaces the start-message TransformationAxis of the previous commit, which was the wrong shape in two ways. DetectorTransformation (common/) mirrors a NeXus NXtransformations axis and holds nothing else: name, type, units, vector, offset, depends_on and the positions themselves. Deliberately without cleverness - the values are either a single number for an axis that does not move or one per image, and nothing derives a position from a start and an increment. That is the point: a producer will later want to report where a stage actually WENT rather than where it was told to go, and a structure that stores start+increment cannot express that. A million images cost 4 MB per axis, which is not a reason to be clever. Hence also the move to the END message: measured positions are only known once the run is over. And hence no metadata version bump, which the previous commit did make. The chain is optional; when it is absent the writer builds the identical chain from the start message, exactly as before. Nothing on the wire changes for a producer that does not send it, so a broker and a writer of different releases still interwork - the constraint the previous version stated is withdrawn. The writer transcribes a chain it is given, without recomputing an angle, which is what makes measured positions possible end to end. JFJochReader_TransformationChain_SentAndBuilt writes the same run both ways and checks the two files read back the same, chi/phi included. CBORSerialize_End_Transformations covers the wire 1:1, asserting the order survives and that a moving axis keeps one value per image while a stationary one keeps a single value.
