Description
Remove the develop flag G1HRRSUseSparseTable as it's never used anyway, and if you need it for some (performance) testing, you need to rebuild anyway as it is a develop flag. At that point (i.e. when you are already taking that much effort) you may as well add a `if (false &&` in the relevant condition manually. A further problem is that the flag does not completely remove the sparse PRTs, they still take memory.
