Uses local Florence2 modules with accelerate-based weight loading and
a custom Florence2Processor for transformers >= 5.0.0, while keeping
the existing loading path for older versions.

In transformers 5.x, forced_bos_token_id was moved from PretrainedConfig
to GenerationConfig. Florence2's custom config accesses this attribute
during init, causing an AttributeError that prevents model loading and
leads to a NoneType crash when the processor is later called.

The old code used list.extend() on the outer (image-index) dimension,causing bboxes from different inputs to be treated as separate images rather than merged into the same image's bbox list.
transformers 5.x introduced two breaking changes that affect the
bundled GroundingDINO BertModelWarper:
1. `BertModel.get_head_mask()` was removed. Added a standalone
`_get_head_mask()` fallback with a `hasattr` check so both
transformers 4.x and 5.x work.
2. `BertModel.get_extended_attention_mask()` changed its 3rd
positional argument from `device` to `dtype`. The old call-site
passes a `torch.device`, which newer transformers interprets as
`dtype=torch.device` → TypeError. Replaced with a standalone
`_get_extended_attention_mask()` static method that also handles
PyTorch 2.9's prohibition of `1.0 - bool_tensor` by explicitly
casting to float32 first.

fixes RuntimeError: Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is False. If you are running on a CPU-only machine, please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU.
