Initial build

Initial Intel Mac build.

Usage:

./doggo <trace_path> <resource_name or partial string> -[-vvv] [--depth=<depthLimit>]

Given a trace_path leading to tracedata json and a query (either a resource name or a partial resource name), displays the spans and children of the sections of the trace that match.

By default, timing information for each span is shown.

-v adds more resource-related information for each span;
-vv adds even more resource-related information, including tags, for each span;
--depth=<depthLimit> allows limiting how many levels down each match the display should go.
