Sample usage

using Nerdbank.Zcash;

// Parse addresses:
var transparent = ZcashAddress.Parse("t1a7w3qM23i4ajQcbX5wd6oH4zTY8Bry5vF");
var sapling = ZcashAddress.Parse("zs1znewe2leucm8gsd2ue24kvp3jjjwgrhmytmv0scenaf460kdj70r299a88r8n0pyvwz7c9skfmy");
var unified = ZcashAddress.Parse("u1vv2ws6xhs72faugmlrasyeq298l05rrj6wfw8hr3r29y3czev5qt4ugp7kylz6suu04363ze92dfg8ftxf3237js0x9p5r82fgy47xkjnw75tqaevhfh0rnua72hurt22v3w3f7h8yt6mxaa0wpeeh9jcm359ww3rl6fj5ylqqv54uuwrs8q4gys9r3cxdm3yslsh3rt6p7wznzhky7");

// Extract the receivers from unified addresses:
SaplingAddress? sapling = unified.Receivers.OfType<SaplingAddress>().FirstOrDefault();

// Construct unified addresses:
UnifiedAddress unified = UnifiedAddress.Create(new[]
{
	ZcashAddress.Parse("zs1znewe2leucm8gsd2ue24kvp3jjjwgrhmytmv0scenaf460kdj70r299a88r8n0pyvwz7c9skfmy"),
	ZcashAddress.Parse("t1a7w3qM23i4ajQcbX5wd6oH4zTY8Bry5vF"),
});
string myUnified = unified.ToString();
