Memongo doesn't work Apple M1 Silicon

[anuj-kumar]

I'm trying to use memongo for application testing on Apple M1 chipset. On running the test, it throws the following error:

panic: memongo does not support automatic downloading on your system: your architecture, arm64, is not supported

anuj ~> go version
go version go1.17.5 darwin/arm64

Two things:

1. This can be solved by specifying the download URL when running on M1:

opts := &memongo.Options{
	MongoVersion: "5.0.0",
}
if runtime.GOARCH == "arm64" {
	if runtime.GOOS == "darwin" {
		// Only set the custom url as workaround for arm64 macs
		opts.DownloadURL = "https://fastdl.mongodb.org/osx/mongodb-macos-x86_64-5.0.0.tgz"
	}
}
mongoServer, err := memongo.StartWithOptions(opts)
