Relation to niseredis

[clue]

After talking to @nrk about this project he shortly after published niseredis, a redis server mock:

https://github.com/nrk/niseredis

It already includes an implementation for quite a few commands missing from this project. However, due to its blocking nature it made some fundamentally different design decisions.

We should look into how (or whether) we can integrate niseredis.

I'm willing to lend a hand if you need help to evaluate an integration of niseredis into this project, and eventually discuss or apply changes to niseredis where needed (it was started mostly just for the fun of it so it's not like I must stick with its current form).
