cargo playdate new generates invalid bundle ID

[paulyoung]

I ran cargo playdate new crates/demo and then cargo playdate run -p demo --device -vvv.

I got the following error. It didn't show up the first time I ran it without -vvv.

       Error Pdc exited with error, code: 1
	stdout: ""
	stderr: "error: Metadata bundle ID not in reverse DNS format (ex: com.panic.b360)\n"
       Error Pdc stderr:
error: Metadata bundle ID not in reverse DNS format (ex: com.panic.b360)

Cargo.toml contains:

[package.metadata.playdate]
bundle-id = "com.demo"

I changed this to bundle-id = "com.demo.demo" and no longer got the error.
