Feature Request. Implement Tag Frequency sorting

[silveroxides]

Would it perhaps be possible to implement tag frequency sorting for custom words similar to how sd-webui-tagcomplete does it?
It uses a local database which it updates with the frequency of the tags from the source site tags are specified to.
This allows for proper aliasing and choosing the most frequent and as a result the most trained alias for any tag.
This also works for the cases where you want to use e6 tags but user isn't that well versed in them
In that case when writing a booru tag in prompt, the user is shown most frequent e6 tag equivalent alias and can choose that instead.
