Python-inspector cannot parse requirements.txt with '\' as end of line character

When a requirements.txt file has been generated with all packages pinned to an exact version and set of hashes, like below:
```python

```

python inspector has the error:
```python
pyparsing.exceptions.ParseException: Expected string_end, found '\' (at char 197), (line:1, col:198)
```

Removing the "\\" from the file completes without errors.
