Python module to parse AWS LoadBalancer and CloudFront logs into Python3 data classes.

CloudFront Example

    >>> from aws_log_parser import log_parser, LogType
    >>> entries = log_parser(log_data, LogType.CloudFront)
    >>> entries[0]
    CloudFrontWebDistributionLogEntry(
        date=datetime.date(2014, 5, 23),
        time=datetime.time(1, 13, 11),
        edge_location='FRA2',
