Introduce paging for functions which returns list

[djordjedjukic]

    let pageItems pageSize pageIndex items =
        let totalItems = Seq.length items
        let totalPages = (totalItems + pageSize - 1) / pageSize
        let pagedItems =
            items
            |> Seq.skip (pageIndex * pageSize)
            |> Seq.take pageSize
            |> Seq.toList // Convert to list here if necessary, or adjust return type to seq<'T> if keeping as sequence is preferred
        { Items = pagedItems; TotalItems = totalItems; TotalPages = totalPages }

type PagedResult<'T> = {
    Items: 'T list
    TotalItems: int
    TotalPages: int
}
