LSP not working on Windows because of file extension

[Dimension4]

It seems the LSP cannot start on Windows because the LSP exe doesn't have a file extension. I've manually renamed c3-lsp-windows to c3-lsp-windows.exe and adjusted the path in extension.js and now it seems to work fine. Not sure why VS Code needs a file extension, running the LSP from the terminal worked fine, even before.

I would open a PR, but I don't know where you get the binaries from, so I can't rename them.

Thanks for the notice, fixed and pushed to vscode.

I take the LSP binaries here https://github.com/pherrymason/c3-lsp/releases
