Wrong handling of rule with wildcard in path

protego == 0.3.1
```python
from protego import Protego

content = """
User-agent: *
Allow:    /*/filter/page=*/$
Disallow: /
"""
robots = Protego.parse(content)
user_agent = "mozilla"

url = "https://example.com/1/filter/page=5/"
print(robots.can_fetch(url, user_agent))
```
returns False instead of True
