+ empty get_slice should return the slice type StdVec
+ set_slice with from >= to should throw
+ set_slice with incompatible iterator and slice sizes should throw

+ use ::allocator_type typedef by default, set as void for std::array

+ shortcut function exposeStdArrayEigenSpecificType now uses Eigen::aligned_allocator<T> for the slice vector

+ sets allocator for the std::vector<T, Allocator> returned by get_slice

+ add eigenpy::array_indexing_suite
+ add eigenpy::StdArrayPythonVisitor
+ add function template exposeStdArrayEigenSpecificType<MatrixType, std::size_t Size>

+ does not exist on all container types

* optional: expose to-value converter for boost::none_t (and std::nullopt_t if possible)

+ add src/optional.cpp to expose none types
+ this allows to have None as a default arg value for functions (also, shows up in stubs)
+ also allows to have none_t return/argument type

* Run pre-commit

+ default is boost::optional<T>
+ add test for boost::optional

This solution should be unified when MSVC compiler will behave properly
