feat(config): Support for pyproject.toml files (#790)

This PR adds support for parsing `pyproject.toml` config files. The convention
for these files is to put any tooling related configuration into the
`tool.NAME` section, so in this case, `tool.typos`. I have verified that the
changes are pulled correctly, even if the `tool.typos` section is not present.

Closes #361
