SQL to YAML Notes

INSERT statements in SQL dumps and scripts are parsed into rows.
Each table in a dump can be written to a separate output file.
When writing SQL, INSERT or UPDATE/UPSERT using a multi-column key can be generated.
The output indent can be set (2 spaces by default).
Flow style ({ } / [ ]) can be enabled or disabled.
Dotted column names can be written back as nested YAML mappings.
