Release 0.6.1

New features:

• The merge_vocab script gained support for directories containing vocabularies created with voc4cat transform --split. This feature is used in gh-actions of voc4cat-template-based vocabularies. #144

Changes:

• The use of logging levels was made more consistent: Success of an operation is now logged for all operation on INFO level. #145
• The log file will now always be written to the given directory. Previously the log file directory depended on the presence of the --outdir option. #144

Bug fixes:

• Sub-command voc4cat docs failed if --outdir was not given. #143 #144
