Add support for automatic retry of failed parameterized tests

In this release, I enhanced the automatic retry feature to include failures of tests under parameterized runners. Previously, enabling automatic retry with parameterized tests would result in a variety of bad behavior.

NOTE: The numbering for this release skips over 15.1.0, which was deleted because I rushed the process and failed to actually merge the related pull request (#102) prior to publishing it. 🤦‍♂️

In addition to this added retry support, I fixed a few bugs I encountered along the way. Here's a summary:

• Create a fresh "atomic test" statement for each post-failure retry attempt.
• Refactor implementation to eliminate duplicate code in Theories runner support.
• Create a new annotation proxy to indicate retried @Theory methods.
• Optimize handling of ignored tests to avoid checking for activation of the automatic retry feature.
• Enhance the method descriptions produced by JUnitParams, adding the test class and annotations.
• Genericize the return type of LifecycleHooks.callProxy, eliminating the need for clients to type-cast the results.
• Expand JavaDoc and add code comments to illuminate behaviors and explain "magic".
