Upgrading to LTI 1.3

[Cvmcosta]

Hello, i came across this project because it uses the ims-lti framework. But this framework does not support the LTI 1.3 standard and it hasn't been maintained in about 4 years. I've recently started a project that implements the 1.3 version of the LTI protocol for tool providers in NodeJs. And since i'm conducting some research using this project i need all the feedback i can get. So it would be really nice if the maintainers could take a look and consider the viability of utilizing it. I could even implement it and submit a pull request for analysis if you're interested. The package is at LTI.JS. Thanks in advance.
