Adding a license to this repo

[carrieeex]

Dear @AFFogarty @musicus @vee-L

As per SSHRC’s guidelines on open data and the contracts signed by DDMAL employees, all of our software is open source. However, not all of our GitHub repos currently have licensing information.

Effective now, we would like to change the license of this repository to the MIT License (currently, it doesn't have any), which is summarized below:

MIT License

You have been included in this issue because you have contributed, at some point, to the development of this repository.

We will wait for two weeks from the date of this notice to address any questions or concerns you may have.

If you don't have any concerns, we do not require any action on your side and will update the license accordingly.

Thank you,
