Fix: Incorrect save/load array size of Town::cargo_accepted

Browse Source 
In 11ab3c4e the number of cargo types was changed from 32 to 64.
The save/load of Town::cargo_accepted was not updated, such that
only half of the data structure is saved/loaded in savegame versions
199 to 218.
Discard and regenerate data from all savegame versions prior to 219.
