Expand upper dependency boundaries

[afermg]

Following #125, I first merged #123 and then created a reproducible environment using build. The additional changes I made are:

• added nix/centrosome.nix with a nix package that builds centrosome (currently from my fork, so we should point to this repo before merging).
• Added flake.nix, which just provides a reproducible environment for centrosome.nix to be installed

finally, run pytest, all tests passed (2 skipped). Logs here.

We may still want to fix the upper boundaries, just to the maximum that is possible today. Let me know if that is the case or if we should leave them as-is.

• Reverted the BuildExtension addition. That came from the PR I piggybacked, now it's not there.
• Limited dependencies too be lower than the next major version (except for skimage, which is lower or equal than the current one because they are in 0.24).

Ran tests again and they run fine.
LMK if there is something else I should adjust.

I updated the commit and hash of the flake too

All tests pass in CP5. Thanks!

Whoops, did some merge conflicts and accidentally nuked everything. Replacing with #127.
