Request for parse_aws_cloudfront_log or parse_w3c_extended_logfile function

[irvintim]

The documentation for parse_regex suggests opening a ticket to request a parse_* function be added for a log format that isn't already available.

My request is for AWS Cloudfront Logs, the format is W3C Extended Log File format. Which is made up of tab-delimited log lines with 2 "comment" lines prepended with "#" at the top of the file, one with a version # and one with a list of the fields. https://www.w3.org/TR/WD-logfile.html

And is further defined on this doc.: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/AccessLogs.html

e.g.:
