Create types for Options

[gandlafbtc]

Functions on CashuWallet can take optional parameters. The list of optional parameters has grown over time, and it would be nice to create types for each of the Options.

eg.:

type SendOptions = {
			outputAmounts?: OutputAmounts;
			proofsWeHave?: Array<Proof>;
			counter?: number;
			pubkey?: string;
			privkey?: string;
			keysetId?: string;
			offline?: boolean;
			includeFees?: boolean;
			includeDleq?: boolean;
}
