Use of adafruit_logging Causes Pico W to Fail to Reload Circuitpython

[jmangum]

While trying to debug Issue #52 found that Circuitpython would not reload at all (i.e. when saving code.py), and ctrl-C would not return me to the REPL. Had to power-cycle the Pico W to restart Circuitpython. Removed the use of adafruit_logging by removing import adafruit_logging as logging from code.py (and all usage of adafruit_logging) from the script and found that Circuitpython now reloads as it should. Very clear to me that adafruit_logging is interfering with Circuitpython reload functionality (in addition to not working when writing to an SD card).
