Improvements to CLI tool

[oliskir]

• [ ] cache every new timestamp parser (request user to specify an identifier name) so they can be re-used in subsequent submissions
• [x] when linking audio files to an annotation job, issue a warning if some of the files were not found in the database
• [x] when the annotations include audio files that are not present in the database issue a warning but add all the valid annotations, instead of exiting with an error
• [x] for boolean (y/N) requests, only allow y/yes, n/no answers
• [x] add "Tag" as optional field in RavenPro template, and make sure it is parsed by the from_raven function
• [x] for annotation jobs, prompt user to specify any new tags
• [x] for annotation jobs, prompt user to specify issues
• [ ] improved error logging/information when adding audio files to database by specifying filenames or csv/txt file
• [x] only prompt user to specify primary sounds for exhaustive jobs
• [x] don't prompt user to specify background sounds
• [x] when viewing annotation jobs, display source/type tags instead of label IDs
• [ ] start by prompting the user if they want to switch to new git branch
• [ ] prompt user at each completed section (new deployment, new job etc.) if they want to commit and push
• [ ] allow multiple options for selecting audio files
  • [ ] search database for existing files based on date range
  • [ ] search database for existing files based on filenames

Some of the suggested improvements should perhaps wait until the CLI tool has undergone a major restructuring.

The new structure would include:

• [ ] A 'main menu' where users can select which table they want to view/add/edit
• [ ] Functionality to jump between the various tables
• [ ] ...

treelib could be used for the purpose of linking menus/sessions in a hierarchical manner. Nodes could optionally have sessions (Python callables) as attributes, or just link to other nodes.
