Cwtch 5 what's new?

Cwtch 5 is a complete rewrite of Cwtch 4, which was mostly a C translation of Lozza.

There is no multi-threading capability. The default hash is 256Mb.

The network is 768->(384*2)->1 SqrRelu trained on Lozza data. Cwtch 6 will have a new 'zero' network trained on Cwtch data.

Search is mostly Fruit era tech. and improving that will be the focus of Cwtch 7.
