EV3/Microbit critical fixes for code freeze (#1354)
* Resolves - BLESession and BTSession should emit PERIPHERAL_SCAN_TIMEOUT #1348. * Resolves - BLESession should handle 'could not find service' error #1350. * Resolves - BTSession should handle 'no peripheral connected' error #1351. * Fixing a typo that caused device scan timeout bugs. * Resolves - Add casting and clamping throughout the EV3 extension #1352. * Fixing a linting error. * Further fixes for issue #1351.
