+/**
+ * A class that provides a typed interface to a byte array.
+ *
+ * TypedByteArray allows you to define a structured byte array with named fields of specific types and sizes.
+ * It serves as a base class for creating custom byte array structures with convenient property access.
+ *
+ * Example usage:
+ * ```
+ * class PersonData : TypedByteArray(
+ *   Type("name", DataType.STRING, 50),
+ *   Type("age", DataType.BYTE),
+ *   Type("height", DataType.SHORT)
+ * ) {
+ *   var name by string("name")
+ *   var age by byte("age")
+ *   var height by short("height")
+ * }
+ * ```
+ *
+ * @param types The types that define the structure of the byte array.
+ *              Each type has a name, a data type, and optionally a size.
