Add Magic::from_params 

Currently `Magic` has per network consts but no way to dynamically get
the magic bytes for a network. Note also that we are currently trying to
reduce the usage of `Network` in the public API.

Add a public constructor to the `Magic` type that accepts a `Params`
parameter to determine the network to use.
