Show `ENTRIES` block

[Goooler]

R8 shrinks all dirs in JARs, it would be great to have a block to show entry count diffs. Like:

 OLD: ktfmt-0.65-SNAPSHOT-with-dependencies-before.jar
 NEW: ktfmt-0.65-SNAPSHOT-with-dependencies-patched.jar

        │              compressed              │          uncompressed

I guess that's the "other" section in the diff? I wonder if we can attribute those to something other than "other" to make it clear they're responsible for the size diff, too.
