Add additional input/output methods to the `vrs-annotate` CLI

User should be able to pass in a newline delimited file/stream of HGVS and SPDI expressions and receive newline delimited Allele JSON records (JSONL) as an output file/stream.

Consider also changing the `vrs-annotate` CLI name to something else like `vrsify` or something.

Start by locating the vrs-annotate CLI entry point and reading its existing input and output handling. Trace how HGVS and SPDI expressions are parsed and how Allele JSON is emitted; done should include newline-delimited stream or file input and JSONL output, with the CLI naming question resolved.
