Merge MAC vendor database from zm_utils into ZoneMinder. Adds entries for
Reolink, Dahua, Hanwha, Buffalo, Google, Sagemcom, and many additional
HikVision/Ubiquiti/Grandstream MACs. Sorted by vendor type for readability.
Removes duplicates from zm_utils source. Preserves ZM-only Uniview and
TP-Link entries. Keeps IC Realtime Dahua control mapping that zm_utils lost.
Updates Vivotek with ePTZ control and normalizes D-Link type name.
34 -> 73 entries.
