devel/py-jellyfish: Prepare for py-maturin >= 1.x

• Relax version requirements and add the additional directive "modulename" to point newer versions of py-maturin to the symbols of the binary module. Otherwise it emits following warning and leads to runtime errors:
  
  [...] Warning: Couldn't find the symbol PyInit_jellyfish in the native library. Python will fail to import this module. If you're using pyo3, check that #[pymodule] uses jellyfish as module name [...]

• No PORTREVISION bump as the package doesn't change.
