Adding the num of segments into TranscriptionInfo

[stsfaroz]

Users will find it useful to know the number of segments.

This will not work, segments is a generator whose length is unknown until it is exhausted, so len(segments) will run the whole transcription just to get the number of segments and then return an empty generator hence the error that is appearing in the CI because the transcription is empty,

Anyway, I don't see why this should be added to the codebase when you can easily do it later after getting the transcription results

@MahmoudAshraf97 I want to do it in cpu , but this len(list(segments)) takes more seconds than the model.transcribe , is there a way to get it faster ?

[MahmoudAshraf97]

As I explained, it is not possible to get the length of the segments before transcription, it might be doable in batched mode but impossible to do in sequential, just get the length after transcription that is the only guaranteed way of doing that
