Interface 'Provider' incorrectly extends interface 'Signer'

[feulf]

I'm using the @compound-finance/compund-js package in my typescript. When I run yarn run tsc -p . it throw this error Interface 'Provider' incorrectly extends interface 'Signer'

https://github.com/compound-finance/compound-js/blob/master/src/types/index.ts#L114.

To make sure this error is not part of my code I started a new project from scratch, added compound-js package, node-ts, and typescript. The moment I import the package it starts throwing the error.
