Add mask resizing to `from_falcon_perception` converter and improve handling of odd-length `bboxes_raw`

Improve error handling in asset downloads: don't retry on 4xx errors or HTML error pages, and raise descriptive `DownloadError`.

Bump version to 0.1.3 in `__init__.py` and `pyproject.toml`.

Add tests for `from_efficienttam` converter and update asset download logic to standardize save directories under `dtmfiles`.

Add `from_efficienttam` converter for EfficientTAM/SAM mask outputs and unify logic with `from_sam`.

Condense and simplify docstrings in detection converters for `from_datamarkin`, `from_florence2`, `from_detectron2`, and `from_ultralytics`.

Add `from_falcon_perception` converter for Falcon Perception model output with RLE mask decoding and unified detection handling.

Update asset download logic to construct URLs dynamically, preserve path structure, and standardize save directory under `dtmfiles`.

Refactor `Buffer` logic in end-to-end test: add `results` initialization, update method usage, and enhance validation.

Update `smoother.py` with buffer improvements, validation for `temporal_weight_decay`, and variable adjustments

Refactor `Buffer` class to use `deque` for improved buffer management and replace prints with warnings.

Add `COCO_CLASSES` constant to `pixelflow` for consistent class label mapping.

Add `DisplayExit` exception and `quit_key` parameter to `display_video` for controlled termination

Add `class_names` parameter to detection converters for customizable class label mapping.

Fine-tune `pixel_size` scaling in `utils.py` for improved annotation precision.
