Logger's receiverThread can't be recovered after calling end(). #187
Description
Describe the bug
The org.littletonrobotics.junction.Logger class uses a ReceiverThread and starts in it start() and terminates it in end(). Once terminated, the thread can't be recreated and would need to be reinitialized. Because it is initialized as a private static final field, it can't be reinitialized, and therefore, Logger can't be reused after Logger.end() is called, such as through the LoggedRobot.endCompetition() method. This makes automated end-to-end integration tests unpractical.
Expected behavior
Calling Logger.start() should create a new instance of the receiverThread for reuse in automated testing.

Additional context
I am working on simulating robot code similar to this WPILib example: https://github.com/wpilibsuite/allwpilib/blob/main/wpilibjExamples/src/test/java/edu/wpi/first/wpilibj/examples/armsimulation/ArmSimulationTest.java but am unable to due to Logger not being able to restart properly.
