* feat: add Nikon Z Picture Control support * refactor: Consolidate Fujifilm and Nikon MakerNote parsing logic and remove unused code and comments. * fix: decode film parameter before fetching photo data. * fix: decode URL-encoded film parameters for improved routing * feat: Add default set of Nikon Picture Controls for consistent labels and allow for Picture Controls not already in the database to be picked from the drop down. * feat: Add camera make context to film components for conditional Fujifilm simulation display
