adam_flume_diagnostics_object

ADAM, FLUME diagnostics class definition: conservation and div(B) histories.

Writes one row per save step to <output_basename>-conservation_history.dat: iteration, time and the volume integral of every conservative variable. MHD runs also write, on the same cadence, <output_basename>-divb_history.dat: iteration, time, max|div B|, sum |div B| dV and the maximum over the seam-local cells (issue #41, D-10, section 9). Rows are written as they come, nothing is accumulated in memory. The values are computed (and MPI-reduced) by the backends; only rank 0 writes.
