update to a maintained through?

[ljharb]

Hi! You depend on through, an excellent package that unfortunately has not been maintained since 2018. I've forked it as https://npmjs.com/@ljharb/through so that I can maintain it (with @dominictarr's blessing), and am using it in https://npmjs.com/tape.

Would you be interested in a PR that switches this project to using my fork instead of the original? It's effectively identical, but it'd ensure any vulnerabilities will be addressed in the future.
