Merge branch 'dev'

- Add :not([data-fancybox]) to pjaxExclude to prevent fancybox links from being loaded via pjax
- Refactor series grouping to use a shared hexo._seriesGroups object built once
- Improve performance by avoiding repeated post iteration in both tag and helper
- Version bump to 5.6.1
