Demonstration of printing elapsed time for every exec()

With most recent commit, an example of what is printed when the timing trait is enabled:

polyfilter = ops.PolyFilter(
    name="custom_poly1D_name",
    timing=True,
)
polyfilter.apply(data)

Output:

TOAST INFO: Begin custom_poly1D_name (PolyFilter) exec()
TOAST INFO: End custom_poly1D_name (PolyFilter) exec() in 0.01 s
TOAST INFO: Begin custom_poly1D_name (PolyFilter) finalize()
TOAST INFO: End custom_poly1D_name (PolyFilter) finalize() in 0.00 s

I really like this. Only one question: should finalize() also report the time sense the first call to exec()?

Based on offline discussion, most recent commit just prints one message at the start of first call to exec() and then the timing at the end of finalize():

TOAST INFO: custom_poly1D_name (PolyFilter) starting...
TOAST INFO: custom_poly1D_name (PolyFilter) applied in 0.01 s
