[EL] AHS Class 373 Logo patch 1.0.1

Thank you as always! That will be really useful, even if it looks a little bit flashy (I don't know if you have used the official colours, but still looks really good, here are two links for the official colours of SNCF rolling stock: https://www.amf87.fr/railcolor.htm & http://interfer-trains.com/index.php?id_product=649&controller=product)

That makes the eurostar less bare with the logo.
