Added /theaters to /Infrared

[MarkCyber]

Hi UberGuidoZ! I have added /infrared/theaters to the main infrared directory. This folder contains 2 .ir files for Barco and Christie brand projectors, which are the most common type of projectors found in theaters. I did not see these brands listed previously, so I figured it was time for another contribution! And of course, this is for educational purposes only. I do not condone testing without prior authorization. Thank you!
