Add DeepBreath model as task

[Annie-LiGHT]

AIM To extend the availability of our (soon to be published) DeepBreath 💨 model to DISCO

CONTEXT

• DeepBreath is a deep learning model that predicts the presence of childhood respiratory diseases from lung auscultation audio.
• As a proof of concept that DISCO can be used to extend data and model access in scientific publications, we would like to add DeepBreath (without weights, as those have IP value to our collaborators at HUG) to DISCO as a publicly accessible task
• Thus allowing us to make the first published data availability statement citing DISCO

NEED @walid

1. Convert DeepBreath from Pytorch to tf.js (repo: https://github.com/epfl-iglobalhealth/DeepBreath-disease-Julien)
2. No need to add pre-processing which is complex (just add the pre-processing requirements to the task description with a link to the required code)
3. Eventually link to the publication and a small public train set tbd

(secret aim: Just making this an issue so that we can have the satisfaction of closing it later 😛 )
