CanMessage class
A wrapper around a NativeCanMessage.
This class allows you to handle CAN frames allocated natively, or allocate them yourself. When allocating natively, use CanMessage(). When receiving a pointer to NativeCanMessage, use CanMessage.fromPointer.
Be sure to call dispose when you're done with the message. Once disposed, the fields of this class will return garbage data or segfault, so you should be careful to only dispose when you are truly done with the message.
