Grpc 1.45+ support (#157)

* nixpkgs.nix: Bump to 2022-04-22.

* release.nix: Unmark data-diverse as broken.

* *.nix: Adjust to nixpkgs update.

* cbits: Adjust to removal of insecure build.

See grpc/grpc#25586

* Do not make secure connections mandatory

Instead of making secure connections mandatory, use insecure
credentials to keep existing API unchanged.

* release.nix: Make sure .sh scripts are executable before wrapping.

It seems as though the `./Setup sdist` now unsets the executable bit.

* README: Update supported gRPC version.
