🐛 sign(0) was returning 1 instead of 0 with use_dll
...
The C99 copysign() function was used in the generated C output, but that
function does not correctly handle zero. Replace it by a custom sign()
function.

Various filesystem refactorings
...
– DataTree::packageDir() now takes a std::string_view, returns a
std::filesystem::path, and no longer creates that directory
– DataTree::writeToFileIfModified() now takes a std::filesystem::path as
argument
– Do not call DataTree::writeToFileIfModified() for generating MATLAB/Octave
files, since it does not work (the directory inside which the file is written
has been deleted by the preprocessor just before)
– Consistently use DataTree::packageDir() everywhere (for compatibility with
planner_objective)

Simplify strsplit() using std::string_view
...
By the way:
– improve the semantics by having a consistent treatment of empty substring
components (previously, only the last one was ignored)
– move it to DataTree to make it more accessible from elsewhere (even though
ideally it should be in a “utilities” namespace).

New preprocessor option “nocommutativity”
...
This option tells the preprocessor not to use the commutativity of addition and
multiplication when looking for common subexpressions.
As a consequence, when using this option, equations in various outputs (LaTeX,
JSON…) will appear as the user entered them.
There is however a potential performance cost to using this option, yet to be
determined.
