Trace view is prohibitively slow

### Description

We want to use the trace viewer to guide firmware rehosting efforts for FIRE, but the traces are too long for angr-management to load currently. (At least, I waited an hour or so and it didn't finish, though it also didn't appear to crash.) For example, a realistic trace encountered when working on the drone rehosting has 5 million basic blocks. I don't have time right now to profile/improve performance myself. FWIW, Tenet also chokes on a trace this long.

### Steps to reproduce the bug

Load this trace file against the Greensight 1B flight controller firmware.
