Description
Some things are depricated in new Eigen: there are warnings like
```
CXX eigen.cpp
../../../../../../Macaulay2/e/eigen.cpp:410:31: warning: 'BDCSVD' is deprecated: Options should be
specified using the class template parameter. [-Wdeprecated-declarations]
410 | Eigen::BDCSVD svd(AXmp, Eigen::ComputeThinU | Eigen::ComputeThinV);
```
We can live with the warning until Eigen 6.0... or do something.

Research direction
Start in eigen.cpp at line 410 and inspect the BDCSVD call that produces the Eigen 5.0 deprecation warning. Build the relevant component to identify any other deprecated SVD uses, then confirm the warnings are addressed without changing the routine's behavior.
