[Feature Request] Support for logrotated access.log

[Pingger]

This would be two feature requests in one:

1. Additionally to access.log also parse access.log.1 access.log.2 ...
2. Also support reading from compressed logs access.log.1.gz or access.log.1.zst

This is a feature I need, because after 1 week my access.log is 1.2GiB ... So I would like to logrotate it, but keep the statistics intact. (using logrotate I would then compress it with zstd, or as a workaround use btrfs to compress the logfile)

Btrfs-zstd compressed logfile is not that good, as it only uses level 3 by default:

Type       Perc     Disk Usage   Uncompressed Referenced
zstd        12%      150M         1.1G         1.1G
