Wyatt Alt 5a1c839382 feat(python): expose computed columns and refresh_column ...

add_columns gains a computed= mapping of column name to SQL expression, and
refresh_column fills a computed column's unfilled rows. Both are available on
the sync and async tables:

    table.add_columns(computed={"doubled": "x * 2"})
    table.refresh_column("doubled")

transforms and computed are mutually exclusive, since they commit through
different paths and could half-apply.
