* Introduced environment variable USE_AIS_GET_BATCH to toggle AIS batch loading. * Updated PromptedAudioToTextLhotseDataset to utilize AISBatchLoader when enabled. * Modified LazyNeMoTarredIterator to handle URL-based recordings when AIS batch loading is active. Implement URL-based audio loading using AIStore's Get-Batch API to improve data pipeline efficiency. This allows batch fetching of multiple audio files without local tar archive extraction, offloading processing to AIStore. Signed-off-by: Abhishek Gaikwad <[email protected]>
