Missing account information

[juliangums]

My CAMT53 has some more info on the account. Especially the name attribute is very important for me. The doesn't seem to be an easy way to get it, or am I missing something? I can submit a PR where I create another account class for this and change the logic in this method https://github.com/genkgo/camt/blob/master/src/Camt053/Decoder/Message.php#L56 but we could also just add a method to return the xml of an account?

			<Acct>
				<Id>
					<IBAN>...</IBAN>
				</Id>
				<Ccy>...</Ccy>
				<Nm>...</Nm>
				<Svcr>
					<FinInstnId>
						<BIC>...</BIC>
						<ClrSysMmbId>
							<ClrSysId>
								<Cd>...</Cd>
							</ClrSysId>
							<MmbId>...</MmbId>
						</ClrSysMmbId>
						<Nm>...</Nm>
					</FinInstnId>
				</Svcr>
			</Acct>
