Vendor / Product not exposed in the library

### Description

Hi,

I am currently updating my HeadsetControl-MacOSTray from subprocess calls to libheadsetcontrol.
I have it working but miss the vendor / product which I have in JSON output.
`
      "vendor": "Logitech",
      "product": "PRO X 2 LIGHTSPEED",
`
vendor_id and product_id is there.

Can this vendor and product also be added please ?
