Sequence: Writing map To Work As A Single Generator (Scala 3 Video)

To enable `for/yield` functionality in the `Sequence` class, a `map` method must be defined. The provided error indicates its absence in the current implementation.

The `:_*` syntax allows a collection to be passed as varargs, crucial for the constructor of `Sequence`, facilitating the transformation of elements into a new sequence.
