Support for RFC 5424 time format in syslog messages

[mbiebl]

RFC 5424 [1], which is based on RFC 3339 [2], defines a new time stamp format for syslog messages and is the default in rsyslog [3]
The benefits of this timestamp format are:

• sub-second precision
• contains timezone information
• is sortable
• contains the full date, including the year

A log message looks like this:

2021-12-19T20:35:40.572463+01:00 pluto rtkit-daemon[582]: Supervising 9 threads of 5 processes of 1 users.

syslog messages like this are not properly colorized by grc. It would be great if support for RFC 5424 timestamps could be added to grc.
