Changes for 0.10 - 2024-03-07

• Added 'META_MERGE' key in Makefile.PL Modified clean target in Makefile.PL to clean auto-generated .bs and .o files. Added dependency 'Test2::Plugin::UTF8' for testing without 'Wide character in print ...' messages Test t/20-decode_xs-without-use-utf8.t was judged pointless and was removed -- its job is done by t/10-decode_xs.t. Documentation enchancments.
