Support pocketsphinx 5.0.0

[ftnext]

In review of #625 , I found that we need to support pocketsphinx 5.0.0. 5.0.0 released on this October: https://github.com/cmusphinx/pocketsphinx/releases/tag/v5.0.0

Steps to reproduce

1. Set up virtual environment including pip install pocketsphinx
2. python -m unittest discover

Expected behaviour

All tests passed

Actual behaviour

$ python -m unittest discover

{   'alternative': [   {'confidence': 0.96296197, 'transcript': '砸自己的脚'},
                       {'transcript': '咱自己的脚'},
                       {'transcript': '打自己的脚'},
                       {'transcript': '咱自己的角'},
                       {'transcript': '砸自己的角'}],
    'final': True}

It's been a while, has there been any progress on this in the meantime?

Please someone give an update on the status of this issue. The version before 5.0.0 was https://github.com/bambocher/pocketsphinx-python which has been archived for quite a while and is unmaintained. It really shouldn't be used any more but so far this package can not use anything more recent.
