ENH: additional in-place clamp_min(), clamp_max() field methods

Browse Source 
- these already existed for a single value, but now handle the full
  field. This is more memory-friendly.

      fld.clamp_min(lower);  OLD: fld = max(fld, lower);
      fld.clamp_max(upper);  OLD: fld = min(fld, upper);
