gh-35555: update eclib to version 20230424

<!-- Please provide a concise, informative and self-explanatory title.
-->
<!-- Don't put issue numbers in the title. Put it in the Description
below. -->
<!-- For example, instead of "Fixes #12345", use "Add a new method to
multiply two integers" -->

### 📚 Description

Should fix #35535 by updating eclib.  The new version avoids using the
template complex<T> class with T=NTL's RR, which caused problems with
newer compilers, and instead implements its own bigcomplex class.

]`. -->
