Adding dora-record script

[haixuanTao]

What this does

This PR adds a script to convert dora-record data into lerobot format using push_to_hub script.

How it was tested

Current test are done on ALOHA arms using dora-arms https://github.com/dora-rs/dora-arms

How to checkout & try? (for the reviewer)

To try it out you will find an example folder of what dora-record will output here

And you should be able to do something like:

python /lerobot/scripts/push_dataset_to_hub.py \                                                                                                                     
--data-dir 018f8b52-7414-7340-8f1e-d172f2f4ae2f \
--dataset-id dora-arms \
--raw-format dora_record \
--community-id haixuantao

But I wasn't able to do so, with error in the likes of:

Traceback (most recent call last):
