Create a Ruby program for managing a bookstore's inventory system. The inventory information is stored in a text file named "bookstore_inventory.txt." Each line in the file represents a book with the following format: "ISBN, Title, Author, Genre, Quantity, Price." The program should allow the user to add new books, update the quantity of existing books, and display the total value of the inventory. Ensure that the program checks for the existence of "bookstore_inventory.txt" and handles cases where the file is empty. Utilize functions to organize your code effectively, with comments explaining each function's purpose. You can use data structures like dictionaries or lists to store and manipulate inventory data. The program should output the updated inventory information to a file named "updated_bookstore_inventory.txt." Ex: bookstore_inventory.txt: 978-1982110567, To Kill a Mockingbird, Harper Lee, Fiction, 30, 8.99 978-0141439587, 1984, George Orwell, Fiction, 25, 10.99 978-0765326355, The Name of the Wind, Patrick Rothfuss, Fantasy, 20, 12.50 (updated_bookstore_inventory.txt after adding 10 copies of "The Great Gatsby" and updating the quantity of "1984" to 30) 978-1982110567, To Kill a Mockingbird, Harper Lee, Fiction, 30, 8.99 978-0141439587, 1984, George Orwell, Fiction, 30, 10.99 978-0765326355, The Name of the Wind, Patrick Rothfuss, Fantasy, 20, 12.50 978-0743273565, The Great Gatsby, F.
