jc - JSON Convert `/proc/pagetypeinfo` file parser

Usage (cli):

    $ cat /proc/pagetypeinfo | jc --proc

or

    $ jc /proc/pagetypeinfo

or

    $ cat /proc/pagetypeinfo | jc --proc-pagetypeinfo

Usage (module):

    import jc
    result = jc.parse('proc', proc_pagetypeinfo_file)

or

    import jc
    result = jc.parse('proc_pagetypeinfo', proc_pagetypeinfo_file)

Schema:

    {
      "page_block_order":             integer,
      "pages_per_block":              integer,
      "free_pages": [
        {
          "node":                     integer,
          "zone":                     string,
          "type":                     string,
          "free": [
                                      integer  # [0]
          ]
      ],
      "num_blocks_type": [
        {
          "node":                     integer,
          "zone":                     string,
          "unmovable":                integer,
          "movable":                  integer,
          "reclaimable":              integer,
          "high_atomic":              integer,
          "isolate":                  integer
        }
      ]
    }

    [0] array index correlates to the Order number.
        E.g. free[0] is the value for Order 0

Examples:

    $ cat /proc/pagetypeinfo | jc --proc -p
    {
      "page_block_order": 9,
      "pages_per_block": 512,
