[Issue 105] Update individual resort data format

[Rogibb111]

This PR updates the way that the individual resort data is presented on the individual resort pages. It encapsulates the data in a class that contains JSON arrays with each data point in an object with X and Y keys to be used in the Lit-Graph component. Changes in this PR include:

• A new model for the different DataPoint types with Scala "Enums" representing each data point type
• Minimizing imports in DatabaseModel
• Using DataPointTypes enum in resortModel read
• Created DataPlot case class with JSON write method
• Created GraphData class for converting and housing JSON arrays of DataPointTypes
• Updates resort.scala.html to display JSON arrays of DataPontTypes from GraphData

Fixes #105
