mode 9/10 fixes and very basic seed calculator (#6700)

* mode 9/10 fixes and very basic seed calculator

- improves mode 10 fillup and compacting
- fixes a lua errors mode 10
- fixes mode 9 unloading at trailer bugs
- added a very basic seed calculator with field size
- small adjustment to mode 4 loading at waitpoint

* PR fixes
