Remove pycrypto and iGrill Keys From the Code

[kins-dev]

I put together a short blog post here https://blog.kins.dev/2019/04/igrill-device-support-for-igrill-smoker.html

Basically, the way handshaking is done, if you present a challenge of all zeros, you can simplify the authentication to:

• Present the challenge
• Read the response
• Present the response

You can find tested code in my own project https://git.kins.dev/igrill-smoker

The reason you may want to do this is, pycrypto has a couple of security issues:

• CVE-2018-6594
• CVE-2013-7459

@kins-dev any chance for a fork of this project with some fixes?
I think bendikwa is out...

@niXta1 I could fork it. I separated my first fork into a project because I basically built a whole product.

Hi.
As you might have guessed, I do not have a lot of time to code on this for the moment, but when I do, I spend it on making it python3 compatible.

I am very thankful for the suggestion, and have implemented it on the experimental python3 branch, which i hope to get merged to master not too long into the future.

If you need help with migration to Python 3, I've already done that on my master branch

This is now merged to master.
