Propose to enhance the Traffic Indication Map (TIM) decoding so the partial
virtual bitmap is filter-capable.

A filter like wlan.aid == 132 would match a PS-Poll frame from that client but
will not match the bit set in the TIM map of the beacon.  Since they have to
operate together, it would be useful if filter tools exist to manipulate both
of them.
