date validation doesn't check for leap years or short months

[Stephen-Gates]

I can validate successfully with dates like:

• 1999-02-29 (invalid not a leap year)
• 1999-11-31 (30 days has September, April, June and November)

Hello,

How can I reproduce the bug?

To get me in a direction to look into.

I found the bug using Data Curator https://github.com/ODIQueensland/data-curator however maintenance of the software has slowed due to lack of funding.

@chellem
Please take a look at this example:

const {Field} = require("../src")

const field = new Field({'type': 'date'})
console.log(field.castValue('1999-11-31'))
// Actual: 1999-11-30T22:00:00.000Z
// Expected: TableschemaError is raised
