FastReport Open Source support for .Net 7 on Linux (Non-Windows)

[Reymundo Sua Jr]

Describe the bug
System.Drawing.Common is not supported in Linux. For .Net 6.0, there is a workaround to it but it was removed in .Net 7.0

Workaround in .Net 6.0 is to add it runtimeconfig.template.json

{
   "configProperties": {
      "System.Drawing.EnableUnixSupport": true
   }
}

To Reproduce

1. Add FastReport to the project and call app.UseFastReport()
2. Deploy the project in linux system (App Service for Linux or Linux Docker)

Expected behavior
It should support non-windows

have you tried using FastReport.Core.Skia package? This removes the dependency on System.Drawing https://www.fast-report.com/en/blog/show/fastreport-core-skia/
