Send HUSH3 supply curve to KMD upstream

[leto]

static int32_t didinit,ishush3;
if ( didinit == 0 )
{ set ishush3, didinit=1 }
then in the founders reward check is just looking at ishush3 and not incurring strcmp x 2 overhead
so it can hopefully be put all into the single function

This will allow KMD NN ops to use a single komodod binary
