CPPCheck warning fixes

[HT] Use const vars for sizes and indexes in local assembly.

Since at least gcc-9.1 the original code didn't compile
any longer with error message:
computeSurfaceNodeIDsInPolygonalRegion.cpp:147:48: error: converting to ‘const GeoLib::Polygon’ from initializer list would use explicit constructor ‘GeoLib::Polygon::Polygon(const GeoLib::Polyline&, bool)’
  147 |         GeoLib::Polygon const& polygon{*plys[j]};
      |                                                ^

From reference_initialization page of cppreference.com:
Lifetime of a temporary:
...
 - a temporary bound to a reference member in a constructor initializer list persists only until the constructor exits, not as long as the object exists. (note: such initialization is ill-formed as of DR 1696).

Can now be used via singularity.

Also use own findElementOrError() algorithm.

Selection of tests published in the benchmark-books

Include some suppressions for python, omp, and ld_load.

Add an optional chemical formula flag under the subtree of kinetic reactant

Eve deploy fix

Currently tested on eve. Docker uses 7.4.

- modulecmd is in another directory
- added fatal error when not found on eve

Fixed a few cppcheck/clang-tidy warnings in chemistry library

Iphreeqc CMake and databases updates.

Also reserve memory beforehand.

Change readme file to reflect the origin. Reformat
to the standard 80 chars per line.

Set missing cmake project language specification,
especially for the Var.c file, which must be compiled
