v1.11.2 (2021-08-09)

Fixes and Maintenance

• Fix order of message logging in the IPython input logger. Previously, the
  In log message wouldn't happen until after the command had already finished.
  Now, the In message is logged, then any normal log messages are logged, and
  then finally the Out message is logged, all neatly in order.
• Adjust exception handling output for log files and for centralized logger.
• Log exceptions in threads
• Only log to the centralized PCDS logger when on a PCDS host
• Support stacklevel for centralized logging on Python 3.8+
• Make elog and lightpath optional dependencies for pip
