changelog: dir:// is not in 1.6.1

The folder reader produces a wrong title list on a real DVD — the title
table is read at a sector offset relative to VIDEO_TS.IFO's start, and a
synthesized layout does not put that file where the offset resolves the
same way. Output is silently wrong at exit 0, so the feature is not
wired to the CLI in this release. The library module stays, unreachable,
and ships once both disc families are verified against real content.

 ### Added
 
-- **A disc kept as a folder can now be read directly.** An extracted `VIDEO_TS`
-  or `BDMV` folder — the shape most backup tools produce — works anywhere a
-  disc image does: `dir://Movie/ mkv://Movie.mkv`, or to any other destination.
-  Previously a folder could only be written, never read back. Folders that are
-  already decrypted need no key; one that still carries an `AACS` directory is
-  judged by its content rather than by the directory's presence, so a decrypted
-  backup is not refused for a leftover folder. 3D folders are refused for now
-  rather than produce a silently wrong result.
 - **An existing disc image can now be decrypted without the disc.**
   `iso://In.iso iso://Out.iso` writes a decrypted image from an encrypted one;
   previously the only way to get a decrypted image was to rip the disc in a
