RIR sample rate ignored?

[blaine-fs]

I noticed that fs_rir does not seem to be used after it's read from the RIR file.

Should the RIR be resampled to params['fs'], as the audio has been? Or is this handled elsewhere?

This may not have been an issue with the old 16 kHz RIR's, as they incidentally matched the target sample rate. But I noticed the new data now has 48 kHz RIRs.
