Tests if a value is a BigUint64Array.

@param {*} value - value to test
@returns {boolean} boolean indicating whether the value is a BigUint64Array

@example
var value = new BigUint64Array( 2 );
var bool = isBigUint64Array( value );
// returns true

@example
var bool = isBigUint64Array( [] );
// returns false

@example
var bool = isBigUint64Array( 123 );
// returns false
