Following up on #4412
Added a "kernel" mode for local CAR: when computing the common average referencing, we can simply pre-compute a kernel with 1/local_neighbors for each channel and use it in the
get_traceswith a simple dot product, skipping an inefficient channel loop.This makes the
get_tracesx10 faster (added a skipped test to test locally):
