Returns the first non-empty sequence from the provided arguments, or an empty sequence if all arguments are empty.

    return false // empty sequence
}

result := lo.CoalesceSeqOrEmpty(emptySeq, nonEmptySeq, emptySeq)
// iter.Seq[int] yielding 0, 1, 2

emptyStrSeq := func(yield func(string) bool) bool {

}

    yield("a")
    yield("b")

result = lo.CoalesceSeqOrEmpty(emptyStrSeq, strSeq)
// iter.Seq[string] yielding "a", "b"

result = lo.CoalesceSeqOrEmpty(emptySeq, emptyStrSeq)
// empty sequence (yields nothing)
