jc - JSON Convert iw dev <device> scan command output parser

This parser is considered beta quality. Not all fields are parsed and there are not enough samples to test.

Usage (cli):

$ iw dev wlan0 scan | jc --iw-scan

or

$ jc iw dev wlan0 scan

Usage (module):

import jc
result = jc.parse('iw_scan', iw_scan_command_output)

Schema:

[
  {
    "foo":     string/integer/float,      # best guess based on value
    "bar":     string/integer/float,
    "baz":     string/integer/float
  }
]

Examples:

$ iw dev wlan0 scan | jc --iw-scan -p
