Returns State of the Union addresses.

@param {Options} [options] - options object
@param {(string|StringArray)} [options.name] - name of president(s)
@param {(PositiveInteger|PositiveIntegerArray)} [options.year] - year(s)
@param {PositiveIntegerArray} [options.range] - year range
@param {(string|StringArray)} [options.party] - political party
@throws {RangeError} unrecognized property value
@returns {ObjectArray} SOTU addresses

@example
var speeches = sotu();
// returns <ObjectArray>

@example
