ruby : support new-segment callback (#2506)
* Add Params#new_segment_callback= method
* Add tests for Params#new_segment_callback=
* Group tests for #transcribe
* Don't use static for thread-safety
* Set new_segment_callback only when necessary
* Remove redundant check
* [skip ci] Add Ruby version README
* Revert "Group tests for #transcribe"
This reverts commit 71b65b00ccf1816c9ea8a247fb30f71bc09707d3.
* Revert "Add tests for Params#new_segment_callback="
This reverts commit 81e6df3bab7662da5379db51f28a989db7408c02.
* Add test for Context#full_n_segments
* Add Context#full_n_segments
* Add tests for lang API
* Add lang API
* Add tests for Context#full_lang_id API
* Add Context#full_lang_id
* Add abnormal test cases for lang
* Raise appropriate errors from lang APIs
* Add tests for Context#full_get_segment_t{0,1} API
* Add Context#full_get_segment_t{0,1}
* Add tests for Context#full_get_segment_speaker_turn_next API
* Add Context#full_get_segment_speaker_turn_next
* Add tests for Context#full_get_segment_text
* Add Context#full_get_setgment_text
* Add tests for Params#new_segment_callback=
* Run new segment callback
* Split tests to multiple files
* Use container struct for new segment callback
* Add tests for Params#new_segment_callback_user_data=
* Add Whisper::Params#new_user_callback_user_data=
* Add GC-related test for new segment callback
* Protect new segment callback related structs from GC
* Add meaningful test for build
* Rename: new_segment_callback_user_data -> new_segment_callback_container
* Add tests for Whisper::Segment
* Add Whisper::Segment and Whisper::Context#each_segment
* Extract c_ruby_whisper_callback_container_allocate()
* Add test for Whisper::Params#on_new_segment
