PNG meetings resume Monday

Hello everyone,

I hope you enjoyed the holidays.
This coming Monday, we will resume our PNG meetings.
I will try to update my pull request
<https://github.com/w3c/PNG-spec/pull/248> [1] to address concerns and
unblock the MaxCLL & MaxFALL chunk progress before then.

See you Monday!
