Adds codespell to pre-commit configuration file (#38)

# Description

<!--
Thank you for your interest in sending a pull request. Please make sure to check the contribution guidelines.

Since many of us are working, it makes sense to have a spell checker to ensure we have the right words everywhere. The PR adds [codespell](https://github.com/codespell-project/codespell) to the pre-commit file that allows checking for typos/spellings in the repository.

The tool is available under a GPL-2.0 license and is fetched using its PyPi release. The repo's BSD-3 is compatible with  GNU-GPL family of licenses.  We do not modify any of the codespell's source code. The license file is included in the repository for the sake of completion.

<!-- As a practice, it is recommended to open an issue to have discussions on the proposed pull request.
This makes it easier for the community to keep track of what is being developed or added, and if a given feature
is demanded by more than one party. -->

## Type of change
