getblockstats hash_or_height ( stats )

Compute per block statistics for a given window. All amounts are in satoshis.
It won't work for some heights with pruning.
It won't work without -txindex for utxo_size_inc, *fee or *feerate stats.

Arguments:
1. "hash_or_height"     (string or numeric, required) The block hash or height of the target block
2. "stats"              (array,  optional) Values to plot, by default all values (see result below)
    [
      "height",         (string, optional) Selected statistic
      "time",           (string, optional) Selected statistic
      ,...
    ]

Result:

      "25th_percentile_feerate",      (numeric) The 25th percentile feerate
      "50th_percentile_feerate",      (numeric) The 50th percentile feerate
      "75th_percentile_feerate",      (numeric) The 75th percentile feerate
      "90th_percentile_feerate",      (numeric) The 90th percentile feerate
  ],
  "height": xxxxx,          (numeric) The height of the block

  "medianfee": xxxxx,       (numeric) Truncated median fee in the block
  "mediantime": xxxxx,      (numeric) The block median time past
  "mediantxsize": xxxxx,    (numeric) Truncated median transaction size
  "minfee": xxxxx,          (numeric) Minimum fee in the block
  "minfeerate": xxxxx,      (numeric) Minimum feerate (in satoshis per virtual byte)
