Refactor the Sender creation and Sender traits

[CyberHoward]

This PR refactors the way that the Sender objects are constructed and configured.

The initial PR added a SenderTrait::SenderOptions associated type that allow for building a Sender object.

First, I renamed a few of the traits, types and methods to improve the clarity of the code's structure. Then I split up the SenderTrait into SenderBuilder, QuerySender and TxSender, each with their own scoped functions and types.

With this I refactored the DaemonBuilder(s) to now work as follows:

// Creates a Daemon with the env-var mnemonic. Minimal code required
let daemon = Daemon::builder(chain).mnemonic("...").build()?; // --> Chain now required to build `Builder`

// Creates a `Wallet` with a mnemonic
// Can also customize the `CosmosOptions` to use authz, different hd path, etc.
let my_mnemonic = "...";
let daemon = Daemon::builder(chain).build_sender(CosmosOptions::new(my_mnemonic))?;

// Or create a custom `Sender` or query-only sender
let daemon: QueryOnlyDaemon = Daemon::builder(chain).build_sender(())?;
