…this is fixed, we should be able to proceed to merge and test Chaff bugs in a later PR

Detailed description
The objective is to merge the Chaff bugs into the main branch. The ideal is to have LAVA and Chaff bugs injected simultaneously. Here is the paper.

Note: I do NOT attempt to re-implement the heap-based overflows chaff bug, as this requires glibc 2.24, which uses a really old heap allocator and is therefore difficult to replicate with modern compilers. In a future PR, I will attempt to determine whether there is a generalized way, regardless of the heap allocator, to trigger this chaff bug. However, this will be attempted perhaps in the second paper where I have more time.

Test plan
Unfortunately, this PR got too big. I will have most of the code implementing it ready, but NOT activated just yet.
I want to first kill a bit more tech debt by de-duplicating a few more functions and the LavaPath class.
Then I will also work on getting other binaries working, e.g., file, as well as the other binaries from the Chaff Bug paper.
Once that is done, I'll add CI/CD to confirm the Random Concolic execution and Chaff bugs, while I wait for a mentor to help me cross the finish line
