The TIMEOUTVALUE macro currently has a hardcoded value of 2500 (microseconds),
which limits the ability to use the library at lower CAN bus speeds (e.g. 10 kbps).
At such speeds, a single CAN frame can take longer than 2.5 ms to transmit,
causing `sendMsgBufBlocking()` to timeout even under normal conditions.
This commit wraps the TIMEOUTVALUE definition in a conditional `#ifndef`,
allowing users to override it via compiler flags (`-DTIMEOUTVALUE=20000`) or
a preceding `#define TIMEOUTVALUE` in their own project code before including `<mcp_can.h>`.
This change maintains full backward compatibility while enabling more flexible usage
across diverse CAN configurations.
Example override in PlatformIO:
build_flags = -DTIMEOUTVALUE=20000
Recommended for projects using slow CAN speeds, high bus load, or long arbitration delays.
