Mod Def Pack v1.0.0.2 for Farming Simulator 2019

With this pack the DEF usage gets activated. The base implementation was already done by Giants.
Changelog:
1.0.0.1: Changed fillLitersPerSecond (speed of filling a vehigle/tank) for the DEF storage, MKS8 and MKS32
1.0.0.2: Fixed a relative path for FST990, Increased ModDesc version to 53
A new HUD is added which shows the Def filllevel. Furthermore there is a placeable Def pump, as well as a storage tank for your farm.
For transporting Def the MKS8 and MKS32 is included with the proper fill types. For refilling on the field the Thundergreek FST990 is
added with two filltriggers for Diesel and Def. It's also possible to buy canisters with 25 or 50L of DEF.
To activate the Def usage there must be a DEF Fillunit in the vehicle.xml. This is already the case for a lot of default vehicles.
By default the usage gets multiplied by 1.5, but can be changed directly in the script.
