* somewhaat failed attempt at declaring subterm predicate
I can't really figure out how to link the smt parser to the rest of the
machinenery, so I will stop here and try from the other side. I'll start
implmenting the logic and see if it brings me back to the parser.
* initial logic implmentation
Very primitive, but I don't like have that much work uncommitted.
* parser implementation
* more theory
* Working base
* subterm reflexivity
* a few optimization
Skip adding obvious equalities or disequality
* removed some optimisations
* better handling of backtracking
* stupid segfault
Add m_subterm to the trail
* Update src/smt/theory_datatype.h

* review
* forgot to update `iterate_subterm`'s signature
* fix iterator segfault
* Remove duplicate include statement
Removed duplicate include of 'theory_datatype.h'.
* Replace 'optional' with 'std::option' in datatype_decl_plugin.h
* Add is_subterm_predicate matcher to datatype_decl_plugin
* Change std::option to std::optional for m_subterm
* Update pdecl.h
* Change has_subterm to use has_value method
* Update pdecl.cpp
