Record serialization refinement

[jhugard]

Refinement to #38, F# Record Serialization.

Previous PR #39 exposed to client a set of non-specific names for functions to serialize and deserialize data.

Serializer.serializeTo (for ZeroCopyBuffer)
Serializer.serialize (for ArraySegment)
Serializer.deserializerFrom (for ZeroCopyBuffer)
Serializer.deserialize (for ArraySegment)

This PR refines those calls and names them according to the following pattern:

Serialize.toZeroCopyBuffer (with alias Serialize.toZcb)
Serialize.toZeroCopyBufferLengthDelimited (with alias Serialize.toZcbLD)
Serialize.toArraySegment
Serialize.toArray
Deserialize.fromZeroCopyBuffer (alias fromZcb)
Deserialize.fromZeroCopyBufferLengthDelimited (alias fromZcbLD)
Deserialize.fromArraySegment
Deserialize.fromArray
Etc.

Another benefit is that a serializable record definition only needs to open one module Froto.Serialization.Encoding and client code using such a record only needs to open one module Froto.Serialization !!!
