sometimes I'm getting dates instead of IPs in "Top 20 IP addresses that have been accessing your site:"

First of all, thank you for the script! :)

### Describe the bug

I have noticed that sometimes I'm getting dates instead of IPs in "Top 20 IP addresses that have been accessing your site:" and "Most recent...".

### To Reproduce

Just ran the script with my log.

### Expected behavior

There should be only IPs there

### Screenshots

```
Most Recent top 20 IP addresses:
303 2021/05/18 <--- here
167 66.249.66.11

```

Input log attached (actually just `grep '2021/05/18' ...` part of it) [my.log](https://github.com/bobbyiliev/quick_access_logs_summary/files/6504382/my.log)

Start by running the script against the attached my.log input and inspect the parsing that produces the “Most Recent top 20 IP addresses” and “Top 20 IP addresses” sections. The fix is done when the reproduced output contains only IP addresses in those lists, while the existing access-log summary still works.
