• MPS simulator: Directly use Jacobi SVD if the matrices size are under the threshold, increased the threshold for BDC SVD to 24 from the default 16, this might improve accuracy a bit.

• Since the project is switched to Eigen 5.0, I retried BDC SVD. It looks like the old issues with it that manifested in both the TEBD project and this one are fixed, so I switched to BDC SVD.

• Switched from AVX to SSE2 and increased the jacobi limit for bdc svd to 32, seems more precise this way

• Temporary commit, don't try to run mps tests with this one, they are extended... take more than one hour on my computer. Trying to figure out a BDCSVD & AVX2 bug... also fixed some compiler warnings.

• MPS simulator: Avoid repeated allocations for SVD if not necessary. Increased the limit from where Jacobi is used instead of BDC to 24 (from the default 16)... looks like it solves the precision is…

• Switched to BDC SVD, it's supposed to be much faster than Jacobi... also I found an oddity for very small limit of bond dimension, I'll try this to see how it goes
