Reduce compile time of RunAllen

Stream.cuh (and thus ConfiguredSequence.h) was still included in RunAllen.h even though that's not needed, because StreamWrapper is used. This reduces the compile time and compiler memory usage of building RunAllen.

compiler	memory (master)	compile time (master)	memory (this MR)	compile time (this MR
