Option to preserve empty arrays and objects at "qs.stringify()"

Documentation saying:

Key with no values (such as an empty object or array) will return nothing

However there are cases when this behavior is not desirable. It brings inconsistencies between stringify and parse methods, meaning same object can’t be stringified and then parsed. Example:

qs.stringify({ foo: [], bar: 1 })
// -> "bar=1"

qs.parse("bar=1")
// -> {bar: "1"}

From above example foo field is lost.

Seems like sending a query argument that might be empty (like an array of filter fields) is a pretty common use case. I’m fighting with this now.

This is how most backends interpret it - an empty array means there’s nothing there, so there’s nothing lost. Can you elaborate on the use cases?
