Several dead links in README.md

[flaschbier]

At least the following links are dead or misleading:

• QNAP QIoT device SDK for Python -> https://github.com/qnap-dev/qnap-qiot-sdks/blob/master/python/device/readme.md -> 404
• OS Platforms and hardware compatibility -> unspecific (QNAP homepage)
• Python device SDK: Sample using MQTT,... (3 Links) -> blunt 404 right away
• Additional resources /doc and /tools sections -> blunt 404 right away

It remains unclear whether there is usable software here, especially concerning Python. Personally, I would appreciate a section on what's there and what's not to avoid unneccessary mining. Thank you :).
