basic search does not work at all

**Describe the bug**
```
ENGINE FAILURE: Bing
raise NoResultsOrTrafficError(
search_engine_parser.core.exceptions.NoResultsOrTrafficError: The result parsing was unsuccessful. It is either your query could not be found or it was flagged as unusual traffic
```
I tried the example from readme page. gsearch and bsearch all raise the same error.

the ysearch throw a different error:
```
line 61, in parse_single_result
rdict["descriptions"] = desc.text
AttributeError: 'NoneType' object has no attribute 'text'
```
