Backport PR : fix n^2 performance issue in coalesce_streams preprocessor for n consecutive stream outputs, `\r` fix would be compiled n times, and applied to each ith output (n-i) times. - move pattern to module level - apply replacement after coalescing outputs An example notebook from nbviewer with ~1k outputs that was taking 90 seconds to render now takes 3 seconds.
