Texinfo release size statistics

[Gavin Smith]

I looked at some size stats.  Here they are, in no particular
order.

If we wanted to get the size of the distribution down, the texi2any test
suites would be the first place to start.

There is no reference to t/formats_encodings.t in the ChangeLog, despite
it appearing to be the largest use of space of anything.  However, a
"git log" reveals that it was split from the existing t/converter_tests.t
(on Mon Sep 13 22:03:08 2021), so there may not be much new storage use here.

The large image directories near the bottom of the list also caused
concern.  It seems like an easy win to shrink 

./tests/formatting/out_parser/non_ascii_test_epub/osé_utf8_epub_package/EPUB/images/1-an_image.png

and some other files.  The current size is 517 kB.  Shrinking these
would save a few megabytes when uncompressed.

Tests involving tp/tests/layout/formatting.texi use a lot of space
because they appear to test all of the Texinfo commands at least
four different times, in various contexts using macro expansion.

I'm not saying that this is a problem, but I think it's worth at
least being aware of some basic statistics about the project that
we are putting out.
