TODO: Update to to work with newer versions of socket package

[MaxPower15]

Using socket 0.3.8 (maybe anything after 0.3.5; this is not known to me) results in an error like this when trying to connect:

I updated the mix.exs to restrict the package version from 0.3.1 to 0.3.5, but that kind of fix isn't a good long term strategy. We should update our code to be compatible from 0.3.1 up.
