This change initializes each decoder's random number generator with a
unique seed.
The motivation for this is that currently all decoders are initialized
with the same seed value, 0. The result of this is that for the same
state (logits, probs, and logprobs) they will produce the same output.
This commit adds a check for the CPU backend initialization in the
whisper library. If the initialization fails, an exception is thrown.
The motivation for this change is to make the library more robust and
handle the case when the CPU backend initialization fails.

This commit fixes compiler warnings in whisper.cpp by changing the type
of the loop index variable from int64_t to size_t.
Currently the following warnings are generated by the compiler:
```console
/whisper.cpp/src/whisper.cpp:209:27: warning: comparison of integers of different signs: 'int64_t' (aka 'long long') and 'size_t' (aka 'unsigned long') [-Wsign-compare]
209 | for (int64_t i = 0; i < nels; ++i) {
| ~ ^ ~~~~
/whisper.cpp/src/whisper.cpp:219:27: warning: comparison of integers of different signs: 'int64_t' (aka 'long long') and 'size_t' (aka 'unsigned long') [-Wsign-compare]
219 | for (int64_t i = 0; i < nels; ++i) {
| ~ ^ ~~~~
```
* whisper : enable compiler warnings for src
This commit enables compiler warnings for the src directory. Currently
when the WHISPER_ALL_WARNINGS flag is set to ON is only enables warnings
in ggml, by setting GGML_ALL_WARNINGS to ON. This commit adds the same
compiler flags for whisper's src directory.
The motivation for this is to catch potential bugs and issues early on
in the development process.
* squash! whisper : enable compiler warnings for src
Remove GF_C_FLAGS and GF_CXX_FLAGS from add_compile_options.
* Fix hallucinations during silence
When the predicted tokens end with a single timestamp the the entire 30 segment should be considered as done, to avoid hallucinations for the remaining part of segment.
This behaviour is on par with openai's whisper. Refer to logic related to `single_timestamp_ending` in https://github.com/openai/whisper/blob/main/whisper/transcribe.py
