Recording pagination

[BryonLewis]

resolves #325

• Adds a copy_recordings management command that will take the existing recordings and create a new number of them efficiently by copying data instead of running the entire spectrogram generation. It also has the capability to add some random tags to test tagging and filtering.
  • Example manage.py copy_recordings --count 1000 --tags "foo,bar,test" should copy and create 1000 recordings with a mixure of tags being test foo and bar.
• Modifies the basic /recording endpoint to support vuetify v-data-table-server pagination system
  • tried to make the creation of the output more efficient by structuring and using prefetch for certain fields
• api.ts has been updated with the new request and return results for the /recording endpoint
• Submission Logic moved from Client to Server Side
  • a lot of useState.ts submission logic and computed values have been removed in favor of the get /recordings endpoint returning filtered data. Moving the filtering to the server instead of the client
• Added a new endpoint for getting the unsubmitted neighbors - /unsubmitted-neighbors. This will return the information for the previous and next buttons
• The Recording List uses a default sort and only returns the next 20 recordings. I don't know if we want a full v-data-table-server system or not to be used with this.
• When submitting a recording it re-retrieves the data so we don't need to mark it as complete locally using the emit system
