CTranslate2 3.16.1

Fixes and improvements

• Fix repeated outputs in version 3.16.0 when using include_prompt_in_result=False and a batch input with variable lengths: a typo in the code led to min_length being incorrectly applied

• Release the Python GIL when loading the model
• Initialize the rotary embeddings on the GPU instead of the CPU
• Avoid a copy for the input features passed to the Whisper methods
• Vectorize copy in the Tile CUDA operator
