GCC 13 memcpy warning in can_message.hpp

When compiling modm for an STM32F427 using arm-none-eabi-gcc 13.2.rel1-2, I get the following warnings:

writing to an object of type 'struct modm::can::Message' with no trivial copy-assignment; use copy-assignment or copy-initialization instead [-Wclass-memaccess]

The struct modm::can::Message is missing a copy-assignment or copy-constructor.
