Original issue title: Incorrect concrete projection in H-rep
```julia

When I use `Threads.@threads` to compute `minkowski_sum`, it seems there are some memory allocation errors.
If the code is as follows, it works by `Julia -t 5`.
```
using LazySets
using Polyhedr…

I would like to understand why I sometimes run into a _numerical inconsistency_.
For example, take a 3D shape defined by the following vertices:
```julia
vertices = [ -8.02 -2.955 -2.412

The following example is a reduced version (I removed dimensions and vertices until the error vanishes) of a more complex input.

We run more stable test for polyhedra using `TestSuite`.
Bug fixes:

I encountered Segmentation Fault when using BlockElimination function. The minimum test code is as followed:
```julia

I'm running into an issue where I get a segfault when calling affine_map. I've reproduced the issue in the following code, where I create a weight matrix, bias matrix, and HPolytope and then call Lazy…
