Describe the bug
FieldType.CHAR does not define a javaType for itself and defaults to String.class as it's java type.

To Reproduce
Pick up any FIX message, with a CharField (for example : RootPartyIDSource)
Create a rawstring with any delimiter (example: | )
Try to parse the message using : MessageUtils.parse()
The field returned is a StringField instead of CharField.

Expected behavior
FieldType.CHAR.getJavaType() should return Character.class like other primitive types.

system information:

• OS: [Windows]
• Java version [JDK 17]
• QFJ Version [e.g. 2.3.1]
