Wireshark currently only interprets the ESTA manufacturer code from a dissected
Art-Net packet for Artistic Licence.  It would be useful if these packets could
be labelled.

This requires the population of:

static const value_string artnet_esta_man_vals[]{}

within packet-artnet.c

The official list of ESTA manufacturer IDs can be found at the following
website:
http://tsp.plasa.org/tsp/working_groups/CP/mfctrIDs.php 

It may be worth noting in the code that versions of the Art-Net protocol prior
to 1.4be (19/12/2011) defined the ESTA code as an int16, which has now changed
to two int8 fields in the order of EstaHigh, EstaLow.  As a result, I suspect
devices that output this field using an older version of the specification may
now report the ESTA code backwards (wrong endianness).  I'm not sure if this
can be easily tested for in code or if it will be the case but is worth being
aware of.  

Also, please update:
static const value_string artnet_oem_code_vals[]

I have attached the most recent file from the SDK that contains the required
and most recent OEM values as the list currently in the source code is quite
old.
