Version in __version__

[samuelgarcia]

Hi Jeremy.
Could you had a version attributes in ml_ms4alg, so the version could be introspected from spikesorters ?

We need to report version for benchmark.

At the moment
 python spikesorters.print_sorter_version()  
give

herdingspikes: unknown
ironclust: 5.0.8
kilosort: unknown
kilosort2: unknown
klusta: 3.0.16
mountainsort4: unknown
spykingcircus: 0.9.0
tridesclous: 1.4.2

Cheers
