Mod Holmer Terra Dos T4-40 v1.0.1.5 for Farming Simulator 2022

While playing at HoF 2022, we thought it would be nice to use Holmer Terra Dos there as well.

So I took the Terra Dos provided by Giants on Modhub and made a few changes.

- In this special edition, Holmer Terra Dos can now load carrots and onions in addition to sugar beets.

- two headers / one for sugar beets (original) and one for carrots and onions

- Increased reload speed (shouldn't be slower than Ropa :winking_face: shipped with HoF)

- Adjusted the unload trigger so you don't have to do any tricks when loading into a truck trailer to make it work (this could have happened to the original...)

- Color selection for Terra Dos incl. discs and cutting bars

- Choosing a logo for Hirschfeld friends (you can also without a logo)

- Added passenger seats (original GtX positions don't work here because I had to rename the mod, otherwise the modhub will "update" it with the original Giants version if you press the "wrong" button there).
