v0.22.3 is broken due to funty 1.2 yank

[vmx]

I'm on a project that is still using bitvec 0.22.3. I cannot be built anymore as it depends on funty 1.2, which got yanked.

To reproduce:

git clone https://github.com/filecoin-project/ec-gpu --branch ec-gpu-gen-v0.4.0 && cd ec-gpu && cargo build

I guess the proper fix is to move to bitvec 1.0.1 (I seem to remember some performance regressions, hence I hesitated to upgrade I don't see any performance regressions with 1.0.1). I thought I report it though, in case others run into similar problems.
