v1.11.2.1

Adds support for Keynote 11.2.

Note that between Keynote 10.2 and Keynote 11.2, a number of Protobuf definitions have changed names. keynote-parser does not yet support backwards compatibility. (i.e.: it can only read .key files as the currently-supported Keynote version would, and will write .yaml output with keys that match the current key names - so .yaml files generated with older versions of keynote-parser may not be convertible into .key or .iwa files with this newer version.)

Until this issue is fixed (if it's ever fixed) - to properly read .yaml files created by older versions of keynote-parser, use that older version to read the file, write a .key (or .iwa) file, then read that resulting .iwa file in the newer version of keynote-parser.
