Isahc issue

Hi!
Thank you for your great project!

I try to update it to current cf worker 0.11 (from old 0.7) but compiling failed at the end with 2 crates left from 300+.

The isahc issue looks already solved in your cargo.
So I cant find how to update .

May be you as creator know what may be the problem and how to update it?
