Bytes.newFromBytes

Creates a #GBytes which is a subsection of another #GBytes. The @offset + @length may not be longer than the size of @bytes.

A reference to @bytes will be held by the newly created #GBytes until the byte data is no longer needed.

Since 2.56, if @offset is 0 and @length matches the size of @bytes, then @bytes will be returned with the reference count incremented by 1. If @bytes is a slice of another #GBytes, then the resulting #GBytes will reference the same #GBytes instead of @bytes. This allows consumers to simplify the usage of #GBytes when asynchronously writing to streams.
