Inheriting from 'Editor' in runtime script is causing error CS0118: 'Editor' is a namespace but is used like a type

This is down to Editor assembly not being referenced for new hot reloaded assembly

FSR: Error when updating files: 'AddNewFieldsTest.cs', FastScriptReload.Editor.Compilation.HotReloadCompilationException: Compiler failed to produce the assembly. Output: 'C:\Users\Chris\AppData\Local\Temp\72848fbb3b4645e28394c26e99b3c675.SourceCodeCombined.cs(124,52): error CS0118: 'Editor' is a namespace but is used like a type

Bắt đầu trong Assets/FastScriptReload/Scripts/Editor/Compilation/DotnetExeCompilator.cs, tại khu vực quanh luồng biên dịch được báo cáo ở dòng 309, sau đó theo dõi DynamicAssemblyCompiler.cs và FastScriptReloadManager.cs. Tái hiện lỗi hot-reload của AddNewFieldsTest.cs và xác định assembly mới tham chiếu đến assembly Editor của Unity như thế nào; hoàn thành khi script Editor được kế thừa biên dịch và reload mà không có các lỗi CS0118 và CS0115.
