Config changes: options.stream -> options.input_stream, Turbo -> TurboPass

requested review from @pkoppenb

Hey @nskidmor, thank you for this update that is related to work on FSRs. I left a few trivial comments and some less trivial. I think we need to carefully rediscuss the usage of stream/input_stream for the future, to avoid too many (design) changes later in the year ... Indeed this is now getting a bit messy, I feel, and we should not forget that next year we will have other streams defined, not only the 3 dealt with here. We need to get the code ready to be able to deal with "PhysStreamCharm", "PhysStreamQEE", etc., where the names are simple placeholder examples for the several physics streams we will get out of Sprucing jobs.
