I ended up writing a `in` filter operator, which can compare a field on the
input tiddler to a TextReference to a list, and pass it through if it's in
the list. The code is here https://github.com/mklauber/tiddly-in-filter,
and it's available in my plugin library
here: https://mklauber.github.io/tw5-plugins/
Between that and the wikify macro to build up my filter runs, I was able to
get things working.
