* Optimize vis_heap_chunks command This commit optimizes the vis_heap_chunks command by: 1) precalculating bin labels instead of computing them on demand for each chunk 2) calling pwndbg.gdblib.memory.read once instead of twice in a hot loop For `vis 2000` command ran when debugging python3 shell, the first change cut down the execution time from almost 20s to 5s. Another benchmark, for both 1) and 2) changes showed 19.28s->4.14s timing. The benchmark done is included in this commit in profiling/benchmark_vis_heap_chunks/ so that it can be reproduced e.g. to optimize the function further or to reproduce my results. |

This benchmark was used to investigate performance problems with the vis_heap_chunks command described in https://github.com/pwndbg/pwndbg/issues/1675
