 * A pairing of a {@link MsgPackSerializer} and {@link MsgPackParser} into a single class with convenience read/write methods.
 *
 * <p>
 *    The general idea is to combine a single serializer and parser inside a simplified API for reading and writing POJOs.
 *
 * <h5 class='figure'>Examples:</h5>
 * <p class='bjava'>
 *    <jc>// Using instance.</jc>
 *    MsgPack <jv>msgPack</jv> = <jk>new</jk> MsgPack();
 *    MyPojo <jv>myPojo</jv> = <jv>msgPack</jv>.read(<jv>bytes</jv>, MyPojo.<jk>class</jk>);
 *    <jk>byte</jk>[] <jv>bytes</jv> = <jv>msgPack</jv>.write(<jv>myPojo</jv>);
 * </p>
 * <p class='bjava'>
 * <jc>// Using DEFAULT instance.</jc>
 *    MyPojo <jv>myPojo</jv> = MsgPack.<jsf>DEFAULT</jsf>.read(<jv>bytes</jv>, MyPojo.<jk>class</jk>);
 *    <jk>byte</jk>[] <jv>bytes</jv> = MsgPack.<jsf>DEFAULT</jsf>.write(<jv>myPojo</jv>);
