New types added in 6.13.4 exclude possibility of null in arrays

[pbeshai]

The new types added in #279 are too restrictive as they eliminate the possibility of nulls being in the arrays.

Consider the following acceptable use of parse and stringify:

> const qs = require('query-string')
undefined

> qs.parse('?foo&foo=1&foo&foo=test&foo=&foo')
[Object: null prototype] { foo: [ null, '1', null, 'test', '', null ] }

> qs.stringify({ foo: [null, '1', null, 'test', '', null] })
'foo&foo=1&foo&foo=test&foo=&foo'

While [null, '1', null, 'test', '', null] is a valid value, it does not meet the definition of Stringifiable[] which is (string | boolean | number)[]

That looks like a mistake.

Sorry about that. Let me know if #281 solves this issue.

Thanks! That does the trick 👍
