Expand options with example for saving a Date object with Typescript example

Is your feature request related to a problem? Please describe.
I'm working on using this package for the first time and can't figure out the parser options for a Date object in Typescript

Describe the solution you'd like
Expand the Readme or docs to give options for storing more distinct types

Describe alternatives you've considered
I tried:

  const [birthdate, setBirthdate] = useLocalStorage<Date>(
    'birthdate',
    new Date('2005-04-29')
  )

Which returned a string. That was to be expected.

Then I added:

const birthdateOptions = {
  serializer: (obj: any): string => {
    /* Serialize logic */
    console.log(obj, typeof obj)
    return obj.toISOString().split('T')[0]
  },
  parser: (str: any): Date => {
    /* Parse logic */
    console.log(str, typeof str)
    return new Date(str)
  },
}

Which had to use any cause I could not take Date or string or it would cause a mismatch with the hook.

Additional context
I'm looking to understand this package better and make use of it correctly. So asking for some help here and some improved docs to help the next person.

hey. I think parser signature is (val: string) => T | undefined and the serializer signature is (value?: T) => string, if you don't want to use generics replace T with Date and it should work. give it a go
