[BREAKING] - Refactor NimBLEScan
* General code cleanup * `NimBLEScan::start` will no longer clear cache or results if scanning is already in progress. * `NimBLEScan::clearResults` will now reset the vector capacity to 0. * `NimBLEScan::stop` will no longer call the `onScanEnd` callback as the caller should know its been stopped when this is called. * `NimBLEScan::clearDuplicateCache` has been removed as it was problematic and only for the esp32. Stop and start the scanner for the same effect. * `NimBLEScan::start` takes a new bool parameter `restart`, default `true`, that will restart an already in progress scan and clear the duplicate filter so all devices will be discovered again. * Scan response data that is received without advertisement first will now create the device and send a callback.
