*COMPUTE THE DIFFERENCE OF ALL CURVES BETWEEN RESPECTIVE ONES*
==============================================================

Computes the element-wise difference between successive pairs of curves in a collection — each curve has the corresponding next curve's values subtracted from it. Use this worker when you need pairwise subtraction across an ordered set of curves (e.g., baseline minus variant for multiple channels at once).

     - vector

     - 
     - Ordered collection of input curves (vector format); each curve will have the values of the next curve in the set subtracted from it. Supply two or more curves — the worker processes them pairwise in the order provided.

   * - curves_subtract_between_output_1
     - curves_subtract_between_output_1
     - vector
     - Collection of resulting difference curves (vector format), one per adjacent pair from the input set; the i-th output curve equals input[i] minus input[i+1].
