List of standard data types is out of date

[vertiq-jordan]

It seems like the DSDL has surpassed the listed message types/message contents. It would be great to get the standard types page back up to date.

A couple of things in particular I've noticed are that the StatusExtended message is missing, and the PWM command type (4 in uavcan.equipment.actuator.Command) is missing.

I would venture to guess there are more, but these are the only ones I've directly noticed.

Thanks!
