[Feature Request]: Support for software/hardware timestamp information in CANopen driver

[splatch]

What would you like to happen?

JavaCAN library (see pschichtel/JavaCAN#5) recently introduced support for access to hardware or software timestamp tracked by socketcan interfaces. We can integrate this information within our driver to better track timing of operations.

Currently the PlcSubscriptionEvent should have a getTimestamp() method ... I think this should be what you're looking for.

However am I currently brainstorming a bit on how to refactor the SubscriptionAPI to use one callback per request and not per field, so this API is a bit in flux right now.
