split_on: Python exercise

Your mission

Implement split_on, which cuts values at every occurrence of marker and returns the groups of numbers found between the cuts.

values is a list of int, possibly empty. marker and every element of values can be any int.
Every element equal to marker is a cut and does not appear in the result. The other elements appear once each, in their original order, inside the group that lies between their surrounding cuts.
A marker at the start of values, a marker at the end, and two markers side by side each produce an empty group at that place.
When marker does not occur in values, return a single group holding every element. An empty values gives [[]].
Every group is a new list, never values itself. Do not modify values.
