Consolidate code to geocode a list

[eyeseast]

I do this in three places:

• In geocode_table, which I wrote first
• In the CLI
• In geocode_list, which I needed for the progress bar

This whole block is basically repeated: https://github.com/eyeseast/geocode-sqlite/blob/main/geocode_sqlite/utils.py#L50-L68. Part of the issue is that in the Python API, I'm using log.info and in the CLI I'm using click.echo. Maybe I can abstract that and pass in a print function.
