Two very minor issues with README.md

I noticed two very minor issues with README.md:

1. In the first section ("tplink-smartplug.py") the Usage example references a different name for the python script:

./tplink-smarthome.py -t <ip> [-c <cmd> || -j <json>]

That should be tplink-smartplug.py to match the file in the repo.

2. In the Command table just below that, it lists the system command with description Returns device info. In fact, the info command does that and the system command is not recognized:

$ ./tplink-smartplug.py -t 192.168.0.229 -c system
usage: tplink-smartplug.py [-h] -t <ip> (-c <command> | -j <JSON string>)
tplink-smartplug.py: error: argument -c/--command: invalid choice: 'system' (choose from 'reset', 'schedule', 'antitheft', 'wlanscan', 'info', 'on', 'off', 'reboot', 'countdown', 'time', 'cloudinfo')
$ ./tplink-smartplug.py -t 192.168.0.229 -c info

Awesome tool, loved the Reverse Engineering document.

Thank you, fixed!
