Returns true if the sequence is empty. Will consume the entire sequence to check.

Examples:

go
seq := func(yield func(int) bool) {
    // empty sequence
}
empty := it.IsEmpty(seq)
// empty == true
go
seq := func(yield func(int) bool) {
    _ = yield(1)
    _ = yield(2)
}
empty := it.IsEmpty(seq)
// empty == false
