(devel/R-checkmate) Updated 1.9.4 to 2.0.0. TEST_DEPENDS added, but not enough

# Version 2.0.0
* Expectations now optionally support the package `tinytest`.
 `tinytest` is used as backend if it is attached, otherwise checkmate defaults
  to `testthat`.
  There is now also a vignette on how to setup `checkmate` for `tinytest`.
* Coercion now only affects double vectors.
* Improved error message for type detection in `*List`.
* Removed `*Bit`, the `bit` package is orphaned.
* Fixed documentation.
