product/upstream mismatch

[idomic]

If a user is leveraging the template, editing the get task for instance, to have 2 outputs when originally it was 1. And he forgot to change the consuming task, it'll break with a long error on missing file when actually the reference is missing.

i.e:

- source: get.py
    product:
      nb: output/get.ipynb
      data: output/get.parquet

and having a downstream task features which has this code:

data = pd.read_parquet(str(upstream['get']))
Instead of upstream['get']['data'].

We'd probably need to analyze the size of output input and alert on mismatches.
