Fixes: #13

[emehrkay]

Still doesn't work as described in the README

• I pull this branch
• Created a new project with a go mod init
• Copied the go example from https://docs.ladybugdb.com/get-started/
• Added the go generate command at the top of the file //go:generate sh -c "cd $(go list -f '{{.Dir}}' -m github.com/LadybugDB/go-ladybug) && go generate ./..."
• From within my project, ran go work init . ~/src/go/go-ladybug/ which created a go.work file that points to my local go-ladybug
• Ran go generate ./...
• It created a lib folder in the same directory as my go-ladybug
• That lib folder has lbug.h lbug.hpp and liblbug.dylib
• Run go build
• It complains that ld: library 'lbug' not found in /go-ladybug/lib/dynamic/osx`
• Move the contents of the lib directory to /go-ladybug/lib/dynamic/osx
• Run go build
• execute the executable
• Error go-ladybug/lib/dynamic/osx/liblbug.0.dylib
• Rename liblbug.dylib to liblbug.0.dylib
• Rerun executable
• Things work as expected

download_lbug.sh now calls the upstream script to fetch the archives. CI is passing. Please review the updated README.
