* 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.
* Fix and test ctx disasm when disassembly-flavor changes
* New lib/cache.py: make caching great again
This commit fixes bugs with old caching (memoize.py) and makes it more
readable.

* Add scripts for benchmarking and profiling pwndbg commands
* Fix performance issue in emulator.py
Register to unicorn enum lookup was really ineffective. Replaced with
parsing (consts) on initialization time, and only dict lookup on hot path.
* Fix performance issue in syntax_highlight.
Current code initialized pygments on each syntax_highlight(), which
apparently took some time.
* Minor performance improvements in syntax_highlight
* Memoize IDA availability.
Not sure it this is a valid solution, I have never used pwndbg with IDA.
However, we should not try to connect to ida on each context(), as this
takes 25% of current exec time.
* Explicitly source gdbinit in benchmark scripts.
