whisper : suppress tokens with a regex (#1997)

Browse Source 
* Allow a regular expression to describe tokens to suppress.

Example: --suppress-tokens-re "[,\.]|[ ]?[0-9]+" will suppress commas, periods, and numeric tokens.

Technique inspired by https://github.com/openai/whisper/discussions/1041

* Blind change to fix Java test.
