AGS: Unknown game variant - Blackwell Epiphany 3.3a

[antoniou79]

This was tested with current local build from master HEAD (2.10.0git) with the new version of Blackwell Epiphany on GOG. This update for the game was released only a couple of days ago.

I should note that I'm getting the "3.3a" part from the GOG offline installer application's suffix. Officially the game's version could be something else --- but I can't find a version info from in-game.

The game in 'The Blackwell Epiphany\' seems to be an unknown game variant.

Please report the following data to the ScummVM team at
https://bugs.scummvm.org/ along with the name of the game you tried to add and
its version, language, etc.:
