Make the client/application more robust to network errors

[aome510]

Resolves #150

Summary

This PR adds new changes that make spotify_player more robust to network errors, which allows the application to re-initialize a new Spotify session and reconnect to a new streaming connection after the network errors are resolved.

Changes

• make the client/application more robust to network errors by
  • re-authenticating and initializing a new session if invalid before handling any client requests
  • creating/connecting to a new streaming connection upon a session re-authentication
  • avoiding panics in third-party codes
• update how the application creates a new streaming connection
• update client socket's result/error sending logic
• update the authentication codes to allow code reuse and better error messages
• disable logging when handling CLI commands
