Research direction
Review the blog post at https://rhye.org/post/android profiling flamegraphs/ to understand the Android trace file format. Examine the existing import code in the repository (e.g., src/import/) to understand how other file formats are imported. Implement a new importer following the existing patterns and add corresponding tests.
