fast-jl doesn't work with pip version of 23 and above

[BrunoKM]

If you try to install fast-jl or traker[fast] with pip==23.3.2 or pip==24.0, you get the following error:

The installation works fine on older versions of pip (e.g. pip=22.3.1).

As a workaround you can build wheels in a separate env: python3 -m pip wheel traker[fast]
and then install them in an environment with a newer pip version.

As an aside, this means that the package doesn't work with Python 3.12 and above, since pip<23 doesn't seem to work with newer releases of python (stackoverflow).
