Vl53l0x change address (#1126)
* Added vl53l0x change address and timeout * Added vl53l0x change address and timeout * vl53l0x code cleanup and update test * remove executable bit * lint code cleanup * code review fixes including timeout default to 10ms * Code review cleanup and change a WARN log level message to DEBUG * Fix issue where warn should be temporary * Added name of sensor to warning message * Fix blacklist lint issue * Remove unused import
