- updated to 1.11.1
- updated minimal curl required to 7.85.0
  * Improvements/Fixes:
  - Megatools now install a single `megatools` executable, where former
    `megaXYZ ...` commands now have to be executed as `megatools XYZ ...`.
  - Implemented PKP (public key pinning for mega.nz's API server). Megatools
    no longer use public certificate authorities to verify API server's
    authenticity. If you use software that MITM's your web traffic, megatools
    will not allow this anymore.
