v2.6.0 - jiwer CLI + alignment and visualisation

What's Changed

The return dictionary of jiwer.cer() and jiwer.compute_measures() now has 3 addional keys: ops, truth, and hypothesis. See the alignment section of the README, and the doc-strings of the methods, for more details.

Also adds the jiwer.visualize_measures() to visualize the alignment of all ground-truth/hypothesis pairs.

Finally, the jiwer command is automatically installed upon installation of jiwer, which provides a simple CLI for interacting with jiwer.

• Alignments and a CLI interface by @nikvaessen in #72
