Add an argument in "WHY".

For me it was the PHAT luxon dependency that isn't shaked out from at least cron and node-schedule packages.
We use date-dns and that full luxon looks terrible.

The croner otherwise has not such deps and is relatively compact itself. Why not to add this in "Why another JavaScript cron implementation" part ?

That's composition of the cron pkg from bundlephobia:

Sounds good to me! I'll convert this to a discussion and consider adding this before next release 👍
