RawFrameDataView

Description

Provides access to the Profiler data for a specific frame and thread.

Use RawFrameDataView to retrieve unstructured Profiler samples data for the particular frame.
The order of samples is determined by the order they are generated in the code.

RawFrameDataView can quickly iterate over all samples in the frame without any internal allocations.
