 * Creates a DBC instance that allows for parsing/loading of an existing DBC file
 * or write data to a new DBC file.
 *
 * If loading data from an existing file, simply call:
 * const dbc = new Dbc();
 * dbc.load(fileContent)
 *
 * By default, when a new Dbc() instance is created, the encapsulated data will be empty.
 * If you are wanting to create fresh data you can call createMessage or createSignal to
 * create messages and signals, respectively.
 * Calls to createMessage and createSignal do not by default add the messages to the data,
 * you will need to make subsequent calls to addMessage or addSignal to add the data
 * to the class.
