v0.2.11

get_sysdata() has been deprecated: sysdata.rda comes now uniquely from the package and is not downloaded from lifewatch.be

This means that whenever a new dataset is added to sdmpredictors, a new version of the package shall be released. This is worth as we don't add new datasets that often and the code and the infrastructure to allow that new datasets can be read without a new release takes much more time to debug and maintain.
