Prompt previous tokens for streaming (#163)
* feat: prompt previous tokens for streaming

I used a vector pointer instead of vector itself because it gave weird errors, and why not

* convert vector to use with C api

* feat: remove old refs, check for prompt size

* feat: use better way of getting the pointer

Georgi Gerganov fb8d77f760 stream : add "audio_ctx" parameter
Used to overwrite the audio context size of the Encoder.
For example, setting "audio_ctx = 512" will make it run about 3 times
faster, processing about 10s of audio, instead of 30s.

The transcription quality drops, but this can be used for real-time
streaming purposes where performance is important.

Georgi Gerganov 62b5ff875c stream : add "max_tokens" parameter
Used to limit the number of tokens in a segment.
Useful to battle with word repetition when using partial encoder context

Georgi Gerganov 83c742f1a7 whisper : add option to speed up the audio tempo by x2
Using a Phase Vocoder for speeding up the audio tempo by scaling down
the frequencies in the frequency domain.

This reduces the computation in the Encoder by a factor of 2.
The transcription accuracy is degraded, but for slow to normal speech -
it seems to be still very good.

I think this can find application for real-time transcription - i.e. the
"stream" example.

whisper : token-level timestamp refactoring (#49, #120)
This turned out pretty good overall. The algorithm has been moved from
main.cpp to whisper.cpp and can be reused for all subtitles types. This
means that now you can specify the maximum length of the generated
lines. Simply provide the "-ml" argument specifying the max length in
number of characters

ref #57, #62, #63 : remove unions in C-api + remove designated initializers
We are not ready for designated initializers - many compilers do not
support this C++ feature yet, so removing it's non-trivial usages.

Revert recent sampling change
It does not actually help and seems to produce worse results on some of
the samples

Otherwise, print error message.

Georgi Gerganov d14823582d Try to improve the sampling strategy a bit
It sill fails sometimes when it does not sample a timestamp token for
the entire segment. We now print a message in such cases
