Changes made to tineye engine:
1. Importing logging if TYPE_CHECKING is enabled
2. Remove unecessary try-catch around json parsing the response, as this
masked the original error and had no immediate benefit
3. Improve error handling explicitely for status code 422 and 400
upfront, deferring json_parsing only for these status codes and
successful status codes
4. Unit test all new applicable changes to ensure compatability
A recent update from Mullvad Leta introduced the img_elem. This update
broke the existing logic. Now, by checking the length of the dom_result
to see if it was included in the return results, we can handle the logic
accordingly.
If the flag icon is first, it prevents easily searching the select list on the
keyboard. By moving the icon fully to the right, this will enable a user to
search the select list.
