Parse query strings and extract integer lists from URLs.

from fast_query_parsers import parse_query_string, int_list

url = '/path?key=value&arr=1&arr=2&arr=3'
parsed = parse_query_string(url)
print(parsed)  # {'key': 'value', 'arr': ['1', '2', '3']}

# Use int_list for integer conversion
def parse_ints(url):
    return int_list(url, 'arr')

print(parse_ints(url))  # [1, 2, 3]
