In the interest of making the library usable for both

of network parameters has been replaced with a parameter passed
to the relevant functions. This also moves addres prefix constants
into the network parameters.

Add domain separator to transparent signatures.

Once TZEs are active, we would like to ensure that collisions
between TZE input signatures and transparent input signatures
cannot occur, so we add a domain separator to both.
This also ensures that if TZE inputs are presented for signature
without using the `Future` sighash version, that the signing
code will report an error.
