Fix stringcase dependency with setuptools 78.0.0

[loeschzwerg]

Hi

I wanted to try your package, but it depends on stringcase=1.2.0.
Unfortunately this causes the installation process to fail:

  × Failed to build `stringcase==1.2.0`
  ├─▶ The build backend returned an error
  ╰─▶ Call to `setuptools.build_meta:__legacy__.build_wheel` failed (exit status: 1)
      [stderr]
      Traceback (most recent call last):

      setuptools.errors.InvalidConfigError: Invalid dash-separated key 'description-file' in 'metadata' (setup.cfg), please use the underscore name 'description_file' instead.
      hint: This usually indicates a problem with the package or the build environment.
  help: `stringcase` (v1.2.0) was included because `fastapi-code-generator` (v0.5.2) depends on `stringcase>=1.2.0, <2.0.0`

Please refer to okunishinishi/python-stringcase#42 (i.e. setuptools 78.0.0)

I suggest to replace the package with a maintained one, or hard code given functionality (as it will likely not change)

The package is now migrated to a new repo.
