* netflow: Add observation domain and point to message
The ObservationDomainID and ObservationPointID are two IPFIX fields that
identify the entity that is capturing flows and can be used to enrich
the context around a specific sample.
Parse these fields from the sample and add them to the FlowMessage.

In d1e1ace318 ("Allow Flow Routines to be cancellable (#40)"), the
payload was passed to another goroutine and erased by the next packet
to be received if the goroutine did not process it fast enough. Make
a copy before passing it to the goroutine to fix that.
* adds dataframe link decoding
* can map NetFlow/IPFIX fields and bytes sections from sFlow/packets to any field inside the protobuf
* add CLI argument for loading a mapping yaml file
* Source and destination mac addresses are fed from `NFV9_FIELD_xx_yyy_MAC`
Fixes a bug where the samples were missing either source or destination Mac.
This is supposed to be linked to the sampling direction.
