CAN filter interface

Required methods

`fn accept_all() -> Self`

Creates a filter that accepts all frames.

`fn new_standard(id: u32) -> Self`

Creates a filter that accepts frames with the specified standard identifier.

`fn new_extended(id: u32) -> Self`

Creates a filter that accepts frames with the extended standard identifier.

`fn with_mask(&mut self, mask: u32) -> &mut Self`

Applies a mask to the filter.

A filter matches when: <ReceiveID> & Mask == FilterID & Mask

Example

FilterID: 0b100110111 Mask: 0b000001111

ReceiveID: 0b100110011 ----> Not accepted (3rd bit did not match)

ReceiveID: 0b000000111 -> accepted

`fn allow_remote(&mut self) -> &mut Self`

Makes the filter acccept both data and remote frames.

Clears the RTR bit in the filter mask. Only available for filters with RtrFilterBehavior::Configurable.

`fn remote_only(&mut self) -> &mut Self`

Makes the filter acccept remote frames only.

Sets the RTR bit in both the filter and the mask (if available). Only available for filters with RtrFilterBehavior::Configurable or RtrFilterBehavior::ConfigurableEitherDataOrRemote.
