data preparation scripts for rasr model

[sciai-ai]

Dear @tlikhomanenko i was hoping if you could share the data prep codes for training the rasr model? Also in the arvix paper you mentioned about joint+ Noise model which used rir and other augmentations but in the subsequent published paper only spec augment was mentioned with no noise model. It seems that the published rasr models only supports spec augment as i could only find flags for it. Many thanks
