Now precomputing the quadrature weights and spherical harmonics fully
Precomputing potential from point pieces
Parallelized potential calc with collapse 3
Parallelized spherical harmonics calc with collapse 2
Changed three parallel fors to a single parallel plus three fors
Made potential precalc a collapse 5 instead of 3 loop
Made spherical harmonics precalc a collapse 4 instead of 2 loop
Last for the day
