Draft PR: minimal changes for Windows support

[antonycourtney]

This branch is a minimal variant of the WindowsSupport branch, with a few key differences:

1. The versions of various dependencies and dev-dependencies are kept the same as they are in the node-duckdb master branch.
2. Fixed an off-by-one error in the BLOB handling code in the changes that bring addon/result_iterator.cc up to date with changes in DuckDb master.
3. Fixed the string matched for CLOSED_RESULT_ERROR_MESSAGE to determine when a C++ exception from DuckDb should result in throwing a JS exception.
4. A few minor changes to tests to account for changes in test output when building against DuckDb master.
