Hi @thadguidry.

Thank you so much for reaching out and offering to sponsor my work on this project. I truly appreciate your generosity and support for open-source. However, most of the work was done by original author, my contributions have mainly been minor improvements here and there or updates to keep the project alive.
Again, thank you for considering supporting this project it means a lot me.
