Fix intersect detection using time indexing
Facepalm, obviously absolute array indexes are not going to necessarily align vs. time over multiple feeds/history. Instead use `np.searchsorted()` on whatever curve has the smallest support and find the appropriate index of intersection in time so that alignment always starts at a sensible reference. Also adds a `debug_print: bool` input arg which can enable all the prints when working on this.log_linearized_curve_overlays
