Bmkg

The following release is a minor documentation-based update from the `v1.0.2` update four days prior.
For major notable changes in the initial `v1.x` release, see https://github.com/null8626/bmkg/releases/tag/1.0.2!

- The project's state is now `5 - Production/Stable`!
- I've done a full-fledged rewrite of everything.
- Added a proper test-runner that tests every property to ensure that everything works!
- Switched from using `setup.py` to `pyproject.toml`.
- Switched from using regexes in decoding API types relating to date/time to using the built-in `datetime.strptime`.
- The project no longer depends on the `xmltodict` third-party python library, it only depends on the `xml` module built-in into python.
- Full-rewrite on the docstrings as well.
- Added a `MANIFEST.in` to prevent irrelevant files from being uploaded to PyPI.
- Removed useless functions (especially the ones not available in https://data.bmkg.go.id/)
- Removed several obnoxious badges in the readme.
