Add mfr key with company name based on company ID

[koenvervloesem]

Description:

This adds a mfr key in the JSON output, with a company name based on the company ID in the manufacturer data, using bluetooth-numbers. The logic is:

• if decoded and (compliant and no beacon) -> add company name
• if not decoded -> add company name, let the user decide whether to use the information

In other cases we don't add the company name, because this would be confusing.

A device is considered a beacon when its model_id is one of "ABTemp", "IBEACON", "MS-CDP", or "RDL52832".
