Return the path of the ASR data dir.

This folder is used by some large dataset loaders to avoid downloading the data several times. By default the data dir is set to a folder named ‘asr_data’ in the user home folder. Alternatively, it can be set by the ‘ASR_DATA’ environment variable or programmatically by giving an explicit folder path. The ‘~’ symbol is expanded to the user home folder. If the folder does not already exist, it is automatically created.
