S0024: more than 2 digits for time offset

[emiltin]

format is specified as pp-tt, which limits offset to 99 seconds. see also rsmp-nordic/rsmp_validator#227

[emiltin]

would also be good to move to json arrays instead of the custom list string format

[otterdahl]

Yes. I think the best way to solve this is to use JSon arrays. There are many statuses that suffers this issue. I'm not sure the best way to deal with this.

We could either:

• Use a new status code, e.g S003X which uses the array and deprecate the old S0024.
• Add a new "name" to S0024, e.g. "list" which uses array and deprecate "status"
• Just update in place - but I wouldn't recommend that.
