distmetrics v0.0.4

Fixed

• Fixed transformer to ensure last pre-image always has correct index

Added

• Arxiv link to README
• Installation instructions
• tqdm description for despeckling
• Allow user to disable tqdm for despeckle

Changed

• Renamed load_trained_transformer_model to load_transformer_model
• Renamed inputs to reflect (possible) usage with other polarizations: vv -> copol and vh -> crosspol. The APIs don't change, just the variable name inputs.
