Add --update-incoming-fks CLI flag for transform command

Browse source 
When renaming columns that are referenced by foreign keys in other
tables, the --update-incoming-fks flag will automatically update
those FK constraints.

Example:
    sqlite-utils transform mydb.db authors \
        --rename id author_pk \
        --update-incoming-fks

This will rename the 'id' column to 'author_pk' and also update any
foreign key constraints in other tables (e.g., books.author_id)
that reference the renamed column.
