jc - JSON Convert `/proc/net/tcp` and `proc/net/tcp6` file parser

IPv4 and IPv6 addresses are converted to standard notation unless the raw
(--raw) option is used.

Usage (cli):

    $ cat /proc/net/tcp | jc --proc

or

    $ jc /proc/net/tcp

or

    $ cat /proc/net/tcp | jc --proc-net-tcp

Usage (module):

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

or

    import jc
    result = jc.parse('proc_net_tcp', proc_net_tcp_file)
