Fix for error with type for CloudscraperAPI

[filipjohansson]

I am running version 4.3.0 with the new TypeScript types and I get an error when running await cloudscraper(requestOptions);.

TSError: ⨯ Unable to compile TypeScript:
file.ts(221,16): error TS2349: This expression is not callable.
  Type 'CloudscraperAPI' has no call signatures.

I have tried to fix it with this pull request. It works on my machine. I was trying to run the tests but they were broken before I made my fix.
