Modernize project

Move all configuration to pyproject.toml and remove setup.py.

Use setuptools-scm for automatic version number derivation.

Move all scripts to gdsii.scripts and remove hashbangs and executable
permission. Name main function run() in each script. This allows to use
project.scripts section in pyproject.toml.

Add link to the documentation site.

Declare pyyaml as optional dependency.
