command.wasm : add voice assistant example for the Web (#171) 
Same as the command-line tool "command", but runs in the browser

Also, added helper script "extra/deploy-wasm.sh" and fixed some timing
constants for the WASM examples.

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

f2df9bd768 stream : add "max_tokens" cli arg

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.

62b5ff875c stream : add "max_tokens" parameter

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
