imantics 0.1.12 is bugged

imantics 0.1.12 is bugged, prefer to install older version or master branch (that has nearly all fixes).
```
pip install imantics==0.1.9
or 
pip install git+https://github.com/jsbroks/imantics.git
```
Note that master branch also has a bug, that invert color order from RGB to BGR.
To use a fixed version:
```
pip install git+https://github.com/SixK/imantics.git
```
