Remove rcppparallel

[koheiw]

This is a rather urgent upgrade of the package to avoid crashes caused by memory leaks (segment fault) in the old TBB library in RcppParallel. Since the package does not update the library, we need to link to the new version of the library ourselves.

The library is avaialble in rtools and windbuilder, so Windows users are not affected . Linux users need to install the library header themselves.
