Add syntax for a range of numbers

[jfbrennan]

Would love JSDoc support for defining a valid range of numbers. Like this (syntax is made up):

/**
 * Get the number of days in a month.
 * @param {1..12} month 
 * @return {number}
 */
export function getDaysInMonth(month) {
  ...
}

I know I can do 1|2|3|4|5|6|7|8|9|10|11|12 but defining a range would be so much better for these use cases.
