Create TraceLog (ETLX) without writing to file #1829

I have an EventPipe data capture as a MemoryStream.

I'm able to create an EventPipeEventSource albeit only via the private constructor by setting isStreaming=false (otherwise passing this to TraceLog for conversion fails), but let's not dwelve on this for now:

I'm then able to use TraceLog.CreateFromEventPipeEventSources()

However, I don't want to write the .etlx to a file only to read it again in order to work with the TraceLog instance. Instead, I'd like to initialize the TraceLog directly from the EventPipeEventSource, letting it do the conversion and ending up with a usable instance. Is this somehow possible with existing APIs? If not, what part would be reasonable to change to make this work?
