Version 2.1.5

• Changed behavior from throwing error in case qrbox.width or qrbox is larger than the width of the root element. In such cases the dimension will automatically be truncated to the size of root element and will throw a warning based on verbosity settings. This should address issue#357
• If qrbox is not set in config for either Html5QrcodeScanner or Html5Qrcode the scanning box will default to the size of video stream. From UI perspective there will be no shaded QR scanning box visible to user. This should resolve Issue#343.
• Calling Html5QrcodeScanner#clear() will also clear the UI rendered due to image based scan. This should address issue#193
