Revamped local upload, Segmentation local upload + custom camera parameters

Added

• mask_url can now be a local file for segmentation annotations or predictions, meaning local upload is now supported for segmentations
• Camera params for sensor fusion ingest now support additional camera params to accommodate fisheye camera, etc.
• More detailed parameters to control for upload in case of timeouts (see dataset.upload_predictions, dataset.append, and dataset.upload_predictions)

Fixed

• Artificially low concurrency for local uploads (all local uploads should be faster now)
• Client no longer uses the deprecated (and now removed) segmentation-specific server endpoints
• Fixed a bug where retries for local uploads were not working properly: should improve local upload robustness

Removed

• client.predict, client.annotate, which have been marked as deprecated for several months.
