Hi,
I needed to filter received frames by CAN ID so I've added a
WithFilterReceivedFramesByID()option for socketcan Dial.Thought it might be more generally useful. Let me know what you think.

Provides received frame filtering by ID using the CAN_RAW_FILTER socket option on Linux
See https://docs.kernel.org/networking/can.html#raw-socket-option-can-raw-filter
This is useful when there are multiple devices on the CAN bus and you don't want to dedicate a goroutine to reading and throwing away frames from devices that you're not interested in just so the receive buffer doesn't fill up.
