Coin Mech O/S calculation timing

• This only applies to machines with a coin mech that reports inventory
• VMS users reported that sometimes the Coin Mech O/S reported incorrectly 
• We determined that Gimme VMS correctly calculates Coin Mech O/S = Coin Mech DEX - Expected Coin
• However, the timing of this calculation with users getting DEX provided incorrect data 
• We updated the logic to get DEX files first, then coin mech inventory data
