error: ‘numeric_limits’ is not a member of ‘std’

Hi,
When building with gcc 11.2.1 i get this error:

/home/rob/data/src/FastChem/fastchem_src/init_solver.cpp:90:30: error: ‘numeric_limits’ is not a member of ‘std’
   90 |         j->abundance += std::numeric_limits<double_type>::epsilon()*j->abundance;
      |                              ^~~~~~~~~~~~~~

It looks like you need to add some new headers for gcc 11.

Just adding

#include <limits> 

To to the top of init_solver.cpp fixes things for me

Thanks @rjfarmer for reporting the issue. The problem has been fixed now in the new 2.1 release.
