[BUG] log parser space issue

[jazzl0ver]

Describe the bug

teler cannot parse log having two spaces in a raw. Log example:

Feb  9 09:00:00 192.168.1.1:42814 [09/Feb/2024:08:59:58.051] lb-useast~ backend/api-elb5 0/2000/0/0/1/12/2013 ---- 27/27/2/0/0 0/0 "POST /location HTTP/1.1" 200 {||||||506|Dalvik/2.1.0 (Linux; U; Android 13)} ireq_size=831 resp_size=123 172.31.43.71:4443 192.168.4.169:443 ECDHE-RSA-AES128-GCM-SHA256 TLSv1.2

To Reproduce

log_format: |
  $x $x $x $remote_addr:$x [$time_local] $x $x $x $x $x $x "$request_method $request_uri $request_protocol" $status {$x} $x $x $x $x $x $x

$ ./teler -c ./teler.haproxy.yaml -i ./3.txt

Expected behavior

By removing the space between Feb and 9, things are getting to work:

$ cat 3.txt
Feb 9 09:00:00 192.168.1.1:42814 [09/Feb/2024:08:59:58.051] lb-useast~ backend/api-elb5 0/2000/0/0/1/12/2013 ---- 27/27/2/0/0 0/0 "POST /location HTTP/1.1" 200 {||||||506|Dalvik/2.1.0 (Linux; U; Android 13)} ireq_size=831 resp_size=123 172.31.43.71:4443 192.168.4.169:443 ECDHE-RSA-AES128-GCM-SHA256 TLSv1.2
