Validating an empty ZIP with Arelle does not create an error

[bytelooper]

What happened?

Dear Arelle team and users,

When trying to validate an empty ZIP, Arelle does not create an error.
With the CLI, nothing gets logged to the console. Using the websever, you get the following JSON back:

{
 "log": []
}

I spent some time in the debugger, there appears to be a missing if check for when no entrypoints were found by the method method def filesourceEntrypointFiles.

Thank you very much!
