* tests : add a new benchmark test for long-form audio
Based on "Earnings-21" corpus by Del Rio et al.
Earnings-21: A Practical Benchmark for ASR in the Wild (2021)
https://arxiv.org/abs/2104.11348
This dataset contains 39 hours of long-form speech, sourced from public
earning calls. Each recording contains roughly 50 minutes of English
dialogues between multiple speakers (2-20 persons).
This benchmark suite should allow us to evaluate the performance of
whisper.cpp on long-form audio data.

* tests : apply PR feedback to 'earnings21/README.md'
Based on feedback from Daniel Bevenius.
- Simplify how to download & prepare a Silero VAD model.
- Fix typo: inferece -> inference

* tests : avoid crashing on non-UTF-8 characters
Based on feedback from Daniel Bevenius.
Add 'errors' parameter to open() in order to avoid unhandled
exception on invalid UTF-8 bytes.

* tests : try to interpret the hypothesis as Windows-1252
Based on the discussion in PR#3185.
Evidently Whisper.cpp can represent a quotation mark as '0x93', which
implifies Windows-1252 (Microsoft's ASCII excention), and cannot be
decoded by UTF-8.
Add an explicit decoding loop to address the issue.
