MultiQC v1.35

This release has a very nice shiny new feature for you: the MultiQC Configuration Wizard! 👨🏻‍🎨 🎨

This has an interactive form where you can browse all MultiQC config attributes (there are quite a lot). See them organised with help text and examples. Enter values into the form and have them validated in real time. 📋 ✅

Then see your generated YAML config in a code editor (where you can paste existing configs if you wish). See the config file explained, validated and suggestions for fixes. 📚

The config wizard is a static HTML file that is bundled with the MultiQC repo, but it's easiest to try out online: https://seqera.io/multiqc_config_wizard ✨
