Move copy_batch_to_device to this repo

[Sukh-P]

We want to remove any dependencies the PVNet repo has with ocf_datapipes as we plan to deprecate that repo so it would be good to move this function https://github.com/openclimatefix/ocf_datapipes/blob/main/ocf_datapipes/batch/utils.py#L9 to this repo, can probably live here https://github.com/openclimatefix/ocf-data-sampler/blob/main/ocf_data_sampler/sample/base.py

I would like to take this up @Sukh-P !

Great, thank you @alirashidAR ! You might be interested in doing the linked issue openclimatefix/PVNet#320 after this too

@Sukh-P I wasn’t aware that a PR had already been made, so I worked on the functionality myself. Since I was originally assigned to this issue, I’d be happy to review @zaryab-ali’s PR first. Once it’s merged, I’ll proceed with the next issue on my own.

@alirashidAR since you were assigned to this issue first I would say that the PR you have created can be reviewed first, I have done that now and I am gong to merge it in.

Apologies @zaryab-ali we are updating our contribution guidelines to make this clearer but we are asking people to comment on issues first that they would like to pick up that work, then get assigned, then create the PRs, this is to avoid duplication of work and to make sure the issue being picked up we feel is suitable for the OS community
