	`original→translation→image_without_extension[;text_pos_x,text_pos_y;overlay_path;overlay_x,overlay_y;custom_font;font_size;font_color]`
	formatted .csv file and apply it to all images in the specified folder, after replacing
	background to a specified image at specified coordinates. Text supports colored borders
	and style tags like <b>, <i> (not enabled now) or <color="#ff0000"> in the text.
	All stuff is only configurable in the code.
