SPC-39: MULTI_STATEMENT_COUNT parameter was being ignored (#6)

* Update apiDefinition.swagger.json

- change parameter name case to match snowflake docs exactly

* add StatementHandles

Map new response property for multi-statement handling.

* Apply mappings to GetResults

Same statementHandles mapping that was previously added to ExecSql was applied to GetResults to support Async

* Remove async fixes

These changes are already in dev branch, it was just a temporary change for debugging.
