Description
I'm using the TraceEvent library to process events emitted from Delphi code. Sadly the Delphi compiler does not generate pdb files, but some other file formats, e.g. ASCII based *.map files. Hence, my callstacks can't be symbolized with TraceEvent. Clearly, I could implement the symbol lookup code by myself (this is what I'm going to do), but it would be nice if the library could handle other symbol file formats beside pdb as well.
I understand that the focus is on the MS ecosystem but it would be a nice enhancement to the library if the SymbolReader API would be a open to custom implementations.

Research direction
Start by inspecting the SymbolReader API and its existing PDB-based symbol handling. Define how custom symbol-reader implementations would be supplied and determine the API changes needed to support formats such as Delphi ASCII .map files. Done means callers can provide a custom implementation for symbol lookup without changing the library.
