Implement Hash of object #120

We have to calculate the hash according to the type of Object and return a value.
There is currently M__hash__ but it is not implemented in any Object.

type I__hash__ interface {
	M__hash__() (Object, error)
}

First, we have to implement M__hash__ of numbers and strings(int, float, complex, string).
This is also necessary for the implementation of the dictionary.

I note that in go1.14 the go team have exported the internal hasher

golang/go@bf36219

This makes uint64 hashes which would work very well for our purpose.

That said we could start with a much simpler hashing function.
