Even thought the spec explicitly says that calendar_dates.txt does not need
to be included, in practice its absence very often represents a data error.
Many agencies change their schedules on public holidays but forget to
include that in their feed.
Warning about an empty or missing calendar_dates.txt would alert them to
this, and help ensure that when the file is missing or empty it is really
because the agency wants it to be so.
