Project dependencies may have API risk issues

[PyDeps]

Hi, In MiBand2, inappropriate dependency versioning constraints can cause risks.

Below are the dependencies and version constraints that the project is using

bluepy==1.3.0
pycrypto==2.6.1

The version constraint == will introduce the risk of dependency conflicts because the scope of dependencies is too strict.
The version constraint No Upper Bound and * will introduce the risk of the missing API Error because the latest version of the dependencies may remove some APIs.

After further analysis, in this project,
The version constraint of dependency pycrypto can be changed to >=2.6,<=2.6.1.

The above modification suggestions can reduce the dependency conflicts as much as possible,
and introduce the latest version as much as possible without calling Error in the projects.

The invocation of the current project includes all the following methods.

The calling methods from the pycrypto

Crypto.Cipher.AES.new
