IL2CPP Analytics tool exits with a JsonException when loading a buildreport.json that contains a "dur" value larger than Int64.MaxValue

How to reproduce:

1. Create a new project
2. In the Edit > Project Settings > Player > Other Settings, set Scripting Backend to IL2CPP
3. In the Build Settings window, click Build and build the project for macOS
4. Open the project's "Library/Bee/buildreport.json" in a text editor and replace one event's "dur" value with 18446744073709550000
5. In the Terminal, run "<UnityEditor>/Contents/il2cpp/build/deploy/Analytics --project-directory=<project path> --build-event-id=test --output-path=out.json"
6. Observe the output in the Terminal

Actual result: The Analytics tool exits with "Unhandled exception. System.Text.Json.JsonException: The JSON value could not be converted to System.Int64" at Analytics.IBP.BuildReport.BuildReportData.Load
Expected result: The Analytics tool parses "buildreport.json" and completes without exceptions
