raceWith

Returns the value from flow that emits first.

Both flows are collected concurrently.

Only the first value is emitted.

If both flows have failed, returns the last exception.

Example:

val fast = flow {
    delay(100)
    emit("Fast")
}

val slow = flow {
    delay(1000)
    emit("Slow")
}

val result = raceWith(fast, slow)
println(result)

In this example, the function returns "Fast", because the first flow emits earlier than the second one.
