Editing Accordion register symbols

Accordion register symbols are available as <code>\markup</code> as well as as standalone music events (as register changes tend to occur between actual music events). Bass registers are not overly standardized. The available commands can be found in [{{LILYSTABLEDOC}}/notation/accordion#discant-symbols ‘Discant symbols’ in the Notation Reference].
