Slightly Higher-pitched VO for Alyx Vance

This is a pretty simple mod, all I did was increase the pitch in Alyx's voice by just a little bit. Since Ozioma Akagha already did a good job at making Alyx sound younger, I wanted to see if I could replicate her voice by simply pitch-shifting Merle Dandridge's lines. I hope I got it right. I'd say this voice replacement fits best with mods that change her appearance into her Half-Life: Alyx styled designs or her Half-Life 2 Beta designs.
