`FileNotFoundError` on default `features` path for `model visualize`

[smarbal]

Running model visualize without providing any specific features path produces the following error :

model -v  visualize -e PE-upx-dataset_pe32-pe64_400_kmeans_f92
00:00:03.882 [INFO    ] model              - Test dataset:  PE-upx-dataset(PE32,PE64)

    with open(Features.source) as f:
FileNotFoundError: [Errno 2] No such file or directory: '~/.opt/features.yml'

Replacing the path by /home/user/.opt/features.yml seems to work as a temporary fix.

@smarbal this should be fixed. You can test.

Hi @dhondta ! I had a few issues that I solved (I think) in packing-box/docker-packing-box#29.

But now I stumble on this error :

model -v visualize -e PE-upx-dataset_pe32-pe64_40_kmeans_f90
00:00:03.610 [INFO    ] model              - Test dataset:  PE-upx-dataset(PE32,PE64)

@smarbal the offending line appears at L65 instead of L66 in the current source code, are you sure you updated the package with pbox-update within the container ?

Fixed by #29
