Flow support for Kotlin coroutines

Hello,

I think it would be great to have something like this for coroutines collection.find().toFlow()

There is consumeEach method in CoroutinePublisher, but I think Flow can be more powerful

Maybe something like this with closing resources on cancel

flow {
            collection.find()
                .consumeEach {
                    emit(it)
                }
        }

Thank you for this PR! 😃 I will look at it soon. The <T:Any> is a common problem in kotlin because T alone is equivalent to T:Any?. So:

class A<T:Any>(val a:T)
class B<T:Any?>(val b:T)
class C<T>(val c:T)

fun main() {
    A(null) //compile error
    B(null) //ok
    C(null) //ok
}

I suspect that KMongo is wrong here, I will investigate the problem when looking at your PR 😉

Hey

I opened a PR for that issue please check it out when you have time https://github.com/Litote/kmongo/pull/202

I don’t know how adding <T :Any> to all types will affect current clients of the library. For me it looks like anyway it’s impossible to create …Publisher with T?

So what do you think about that?
