adds Enseo and LG set top box browser user agent headers

Trackjs shows incorrect browser for a couple set top boxes we work with, these regexs will resolve our issue.

Hello @jdibbert, I would recommend to put these UAs into the "device_parsers" section as well as both mainly refer to devices not browsers. Please check the "HbbTV" parsing.
