The fussy package now comes with helper functions to strip down an input
string, removing all extra "tofu" characters added by Consult. This is
also faster than the old hand-rolled solution I had come up with
previously.
Hence I've switch to simpler variant that uses a custom scoring function
that calls `flx-rs-score`, with `str` having been sanitized with the
function assigned to `fussy-remove-bar-char-fn`, which by default is
`fussy-without-tofu-char`.
I've also submitted a PR to fussy that will cleanup the input string
when using flx-rs:
