v2.0.2

Patch / bug fix release

• deseasonalize dependency (not available anymore) to allow installing the package again
• Fix warnings in try-error checks. Some objects have more than a single class/return a string list when provided to the class() function. All checks whether the class of an error is "try-error" is now wrapped in any() to ensure it both works and does not produce any warnings
• Fix bootstrap unit tests. There seems to have been some changes in the sampling algorithms or random number generation of R invalidating the previous bootstrap error estimates. Well, since there was an update to a new major release, this is not too unexpected. Also, the errors of the same order and still reproducible. I updated the values.
