New resources - data collection

#1

Dear all,
to facilitate some aspects of the competition we are going to upload some scripts
in the Resource section of the challenge page.

Today we have uploaded a script collect_data.py and two zip files with data.
The script collects observations from the environment for a certain number of steps
following a “RandomPolicy” policy and then saves them to into 4 different files
(one for each type of observation: joints, contacts, retina images plus a file
for all the actions done).

One of the zip files (2.55GB) contains data from running the script for 100k steps.
When unzipped, it produces 23GB of data (mostly images).

The other zip file contains data from running the script for 10M steps.
When unzipped, it produces about 1.7 GB of data (without images).

New participants may find these files especially useful to get a feel of how the
data might look like when interacting with the environment (randomly) and to do
some training test of neural networks or other approaches.
