Invalid Tag Support

[x-CK-x]

Valid tags are e621 tags that exist in the csv with a count over 1 on the site.

Currently there are two features to add invalid tags to the dataset as post-process steps to editing tags. I.e. edit valid tags & then use the post-process functions on the custom data tab or download tab to insert invalid tags

The Planned Changes

• Create a new supported Invalid Tag/s Category, CSV, Statistics, etc. : this allows the user to add invalid tags directly to the tag editor
• Additional considerations to let the invalid tags be re-ordered however the user desires it to be (this may be it's own feature) : Custom gradio component to let the user restructure the final tags placement in the string easily (Custom Gradio Component for Tag Editor)

[x-CK-x]

• various features across different Tabs will have to be refactored to reflect the changes of including a brand new category to the program
