Fix plot_time_reverse.py time-reverse simulation

Introduction

Introduction from plot_time_reverse.py:

The skull adds aberrations to the beam propagation; phased arrays can compensate for those by having different delays for each element, but estimating these delays can be challenging. One method to estimate the delays is a "time reverse" simulation as described in this Article. This notebook demonstrates the "time reverse" method to estimate the delays. The notebook sets up a scenario with a phased array source and a target and then runs a simulation with the source and target reversed to calculate the delays. Finally, it uses the calculated delays to perform a forward-time simulation.

The time-reverse simulation was still using an old API .add_source so it had both the default source and the

Changes

• Remove the default source from the time-reverse simulation

Behavior

• Tested locally that resulting delays are correct (on the order of 40microseconds)
• Docs generate properly and show the point-source simulation
