Fix ROM title extraction in LoadZelda3 function

Resized the `title_` variable to `kTitleStringLength` to ensure it can hold the ROM title string. Used `std::copy` to copy the ROM title from `rom_data_` starting at `kTitleStringOffset` to `kTitleStringOffset + kTitleStringLength` into the `title_` variable. This change ensures that the `title_` variable correctly stores the ROM title extracted from the `rom_data_`.
