feat: strongly typed messages

[Patch]

Describe the solution you'd like

Send methods should be able to accept two types, one internal for electron-broker that enforces consistent message pattern and data, and the second one that just accepts type for message body

type Message<P extends string, D extends Record<any, any> = {}> = [P, D];

interface Foo {
  foo: string;
}

type FooMessage = Message<"pattern", Foo>

brokerClient.send<FooMessage>("pattern", {foo: "bar"});
brokerClient.send<Foo>("untyped-pattern", {foo: "bar"});

It could be possible to enforce strongly typed message handler as well

Why is this needed
Such a change would make refactoring of messages an ease.
