[yarikoptic]

Closes #172 as empirically shown

@satra do you see a quick way to add a test?

TODO

• compare to current (time has passed; 0.63.0-2-g5faa18a4) normalization in dandi-cli
• after release - adjust dandi-cli to use this normalization implementation

you could use an asset in the tests directory and change the "path" key and subject identifier keys to make the aggregate function raise that assertion you put.

[yarikoptic]

I didn't add assertion in this PR. In this PR such assertion would not be appropriate since code would still allow for multiple subjects from a single path.

[satra]

you could manually assert in the test.

you could manually assert in the test.

well, all tests assert "manually", the question what and in which test.... well -- since confirmed empirically, just feel free to either merge as is, or extend with the test as you see fit.

@yarikoptic - this needs to be updated and merged for #172
