Multiple hours per cast

[EOGrady21]

Currently the app can only visualize one 'hour' of data at a time. VPR casts are often 2- 3 hours long. Functionality should be updated to be able to paste multiple hours of data together for visualization.

Main issues here will be

• allow multiple file uploads
• add more metadata 'slots' for multiple hours
• check if multiple files are uploaded and change processing if required
• loop through files for data processing and then collate them into a single data frame for plotting/ display

Kevin has given more insight into this issue. This app is mainly used for 'on the fly' analysis and looking at one hour at a time is not a problem. The app could be enhanced to include multiple hours together but it is not necessary.
