   Seems there are many missing wheel combos, beginning with #74.

   @zortness How did you build this for 3.14 on Windows x64?

   I used antigravity-cli to figure out how to get it to build, since I'm not familiar with bazel.
   It used bazelisk to interact with bazel, rather than doing it directly.
   It made some minor changes to the build files, some of them probably unnecessary. I'll just paste the diff for you
