@summary Get the local week-numbering year of the given date.

@description
Get the local week-numbering year of the given date.
The exact calculation depends on the values of
`options.weekStartsOn` (which is the index of the first day of the week)
and `options.firstWeekContainsDate` (which is the day of January, which is always in
the first week of the week-numbering year)

@param {Date|Number} date - the given date
@param {Object} [options] - an object with options.
@param {Locale} [options.locale=defaultLocale] - the locale object. See [Locale]{@link https://date-fns.org/docs/Locale}
@param {0|1|2|3|4|5|6} [options.weekStartsOn=0] - the index of the first day of the week (0 - Sunday)
@param {1|2|3|4|5|6|7} [options.firstWeekContainsDate=1] - the day of January, which is always in the first week of the year
@returns {Number} the local week-numbering year
@throws {TypeError} 1 argument required
@throws {RangeError} `options.weekStartsOn` must be between 0 and 6
@throws {RangeError} `options.firstWeekContainsDate` must be between 1 and 7

@example
// Which week numbering year is 26 December 2004 with the default settings?
var result = getWeekYear(new Date(2004, 11, 26))
//=> 2005

@example
// Which week numbering year is 26 December 2004 if week starts on Saturday?
var result = getWeekYear(new Date(2004, 11, 26), { weekStartsOn: 6 })
//=> 2004

@example
// Which week numbering year is 26 December 2004 if the first week contains 4 January?
var result = getWeekYear(new Date(2004, 11, 26), { firstWeekContainsDate: 4 })
//=> 2004
