Remove/Replace examples based on chondro

As chondro is removed from hypseSpec.

Dataset chondro is removed from the devel version of hyperSpec thus this package is not compatible with hyperSpec 0.100.0 or newer as it extensively uses chondro in examples and vignettes. Thus, I added hySpc.chondro as a dependency (2ebd1ba, 9a67761).

If this is not the desired behavior, please do something about this. Otherwise, close the issue.
