Samsung Galaxy S III SGH-T999V - codename "d2tmo" in LineageOS

This device was supported in LineageOS until v. 14.1 (Android 7.1.2). It’s not maintained anymore and the LineageOS d2tmo page suggests to build it and has a link to a build guide.

This particular model was compatible with T-Mobile (USA) and Videotron (Canada) bands.

No particular known issues with the last LIneageOS installed.
