Various bug fixes including a crash in schema_exception destructor
Most notably, this release should be better at bubbling up schema_exception
and preserving error messages from deeper in the query resolution process.
At least on Windows with VS 2019, the copy constructor hiding that I tried for the fix to #63 broke the contract for std::exception
and resulted in a crash when the schema_exception
was copied but didn't invoke the default copy of the _errors
member. That bug has been in there since v3.0.1.
