Maintainership

[hoodie]

Hi Leland,
thanks for this great little library, it is still my favorite for many use-cases.

Since you don't seem to be actively maintaining it much more, would you be ok to make me maintainer of this library?
I would like to add a few things and publish new versions. What do you think?

Thanks

hiho, for transparency I've published what we've added internally at https://github.com/goto-opensource/micro-signals/
