Alt de/serialization of steps and test

Alternative approach for #77

Fixes #71

Closes #77

@bgrosse-midokura Here's an alternative approach. It requires exporting all the step classes. I can change it to have 1 fromState method, but this way is more explicit.

[bgrosse-midokura]

Nice alternative. I think the tradeoff is now clear: either we add the code into the step classes, or we do some hacky almost-property-guessing (my PR).

I think your PR is less surprising and easier to discover for the user. We already have the "routines" separated from the step classes anyway, so we're not mixing too many concerns in the step classes.

I would like to see if we can avoid exporting/exposing those "state" types, I don't think it provides any actual type-safety.

So I would be happy to merge this instead of #77, but this is worthy a small note in the readme, similar to https://github.com/midonet/tssrp6a/pull/77/files#diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5R120

I've added a similar note and expanded on some things

Amazing!

@jbis9051 is it ready to be merged?

[jbis9051]

@bgrosse-midokura I think so.
