General comment:

This SAX breakpoint issue for non z-normed data is related to iSAX-based algos (MESSI, FreSH, Odyssey, Paris, SING).

What happens for other algos (e.g., SOFA/Hercules)? Do they support non-z-normed data? If not, we should extend this pr to fix them as well.

PTAL at the "activeBP" function which is called inside the search functions, I left a comment for that, this worries me a little bit.
