Function to detect which data assets exist for a given mouse ID

**Is your feature request related to a problem? Please describe.**
It can be annoying to have to keep track of which processed data assets are attached to a capsule and/or exist in code ocean

**Describe the solution you'd like**
It would be helpful to have a function that can either look through the data folder or query the code ocean API to identify processed asset names for a given mouse. This could then be converted to a config file for a given mouse to be compatible with the data loader

**Describe alternatives you've considered**
Current alternative is to build a config file containing data asset names for each round of a mouse ID. This is a fine interim solution.

**Additional context**
This is a nice to have, not super urgent. Quality of life thing.
