Fix `pyproject.toml`

[mcw92]

@Filos1992 pip-installing the utis package in a fresh virtual environment with Python3.10 on MacOS fails with the following error message:

Processing /Users/marieweiel/Projects/artist/UTIS-HeliostatBeamCharacterization                                                         
  Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error

  × Getting requirements to build wheel did not run successfully.
  │ exit code: 1
  ╰─> [14 lines of output]
      error: Multiple top-level packages discovered in a flat-layout: ['utis', 'data', 'logos', 'trained_models'].

      To avoid accidental inclusion of unwanted files or directories,
      setuptools will not proceed with this build.

      If you are trying to create a single distribution with multiple packages
      on purpose, you should not rely on automatic discovery.
      Instead, consider the following options:

      1. set up custom discovery (`find` directive with `include` or `exclude`)
      2. use a `src-layout`
      3. explicitly set `py_modules` or `packages` with a list of names

      To find more information, look for "package discovery" on setuptools docs.
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

This is probably due to a misconfiguration in the pyproject.toml file. poetry is a build system on its own and should rather not be mixed with setuptools. For reasons of simplicity, I suggest to adapt this file to match the format of the functional ARTIST pyprojec.toml file which uses hatchling as the build system: https://github.com/ARTIST-Association/ARTIST/blob/main/pyproject.toml

This should work:
