Hi @9thQuadrant
The library doesn't have enough popularity(200 stars/watchers on GitHub and 800 downloads/month on npm registry are good examples). You can take a look at our issue rule for more details 😄 Nevertheless, you are welcome to send a pull request to add your library, we will assist you if you want! This issue will be closed if there is no any response in next 7 days, if there is any other possibility to add this lib, we may discuss to add it.
Thank you for your contribution!
