validate_ami_bags dateCreated json test

[bturkus]

I think there might be something a little off in way that validate_ami_bags is checking for alignment of the dateCreated in Mediainfo vs. as reported in the JSON. I'm getting a lot of this:

ami_md.ami_json: 2021-02-03 13:25:08,102 - WARNING - dateCreated in JSON and from file disagree. JSON: 2021-01-12, From file: 2021-02-03.

But in running the file thru Mediainfo, I'm not seeing the "from file" (in this case 2021-02-03) anywhere:

This is date is running from the following code.

os.path.getctime(self.filepath)

https://docs.python.org/3/library/os.path.html#os.path.getctime

I'm assuming mediainfo might be pulling metadata from the file header instead of the file system. File creation times can be extremely messy, so it would take some additional work to make sure I pull a consistent correct value.

I list this as a warning because it's something that can be useful to know, but isn't critical and shouldn't stop further processing.

Is it OK to close or do you want more investigation on this?
