v1.0.0 — Add PyPy information

- Support Python 3.10
- Drop support for Python 3.6
- Support for fetching information on PyPy versions has been added.  With it come the following changes:
    - The schema used by the database (and thus the URL for the default database) has been modified
    - `PyVersionInfo` has been renamed to `CPythonVersionInfo`
    - A new `PyPyVersionInfo` class has been added
    - A new `VersionDatabase` class has been added, containing a `CPythonVersionInfo` instance and a `PyPyVersionInfo` instance
    - `get_pyversion_info()` is now `VersionDatabase.fetch()`
    - The command-line interface now takes a `--pypy` option for showing details about PyPy versions
- The `unreleased` argument to `major_versions()`, `minor_versions()`, `micro_versions()`, and `subversions()` has been removed; the methods now return all known versions, released & unreleased
- `release_date()` now returns `None` for any known version whose release date is unknown, whether it's been released yet or not.  Use `is_released()` to determine whether such a version has been released.
- `eol_date()` now returns `None` for any known version whose EOL date is unknown, whether it's EOL yet or not.  Use `is_eol()` to determine whether such a version has reached end-of-life.
- Moved documentation from README file to a Read the Docs site
