pyproject.toml: use dynamic dependencies (#38)

* pyproject.toml: use dynamic dependencies

+ requirements.txt:
   - move the packaging related dependencies into tests/requirements.txt file
   - remove `matplotlib` as it's only used in the obsolete functions in utils.py, which is not used at all

+ pyproject.toml:
   - use dynamic files for dependencies and optional dependencies, to avoid duplicating the list of dependencies, to be consistent with mintpy
   - use dynamic files for readme as well

* tests/requirements.txt: add matplotlib
