Update pd-lua to latest from git (bugfixes in lexpr and ltabfill examples).
Hi Jonathan, I just noticed these while testing some pd-lua stuff with the latest binaries from CI on Mac and Windows this morning. Sorry, I didn't notice these earlier, because those examples work without a hitch on Arch. But they are broken everywhere else, including Ubuntu. ;-)
Therefore this hotfix PR. I hope that this can still go into the imminent 2.5.0 release. Otherwise I'm afraid that we'll have to release 2.5.1 pretty soon. (Yes, the broken modules are only examples, but they are really important examples!)
