[WIP] Implement first outline of real time CI retrieval from Electricity maps

[tillenglert]

Draft of real time ci retrieval, based on location!

So far only location of Germany is pulled (hardcoded), we need to see how to actually implement access, and check what kind of location/region codes we use. Apart from that usage of token is used, and if no access to the internet is given the ci table is used to collect the ci.

Would need to check if API call for each Nextflow run would cause problem and how to circumvent this.

Some comments what needs to be done here:

1. First of all ElectricityMaps needs to be contacted to check in
   1.1. if their servers can handle api calls masses if all nextflow pipelines would use the plugin.
   1.2. if we can distribute their data like that (we do not necessarily use one api key for all, but each user would (optionally) register and create their own API access token.
   1.3. We would need to access yearly data and aggregate it to a table which can be used offline (or without access tokens)
2. We need to align our location coding to ElecricityMaps. Therefore, we would need a backup table (mentioned in 1.3) that can be used for offline runs or users without api access. The user would then choose their region based of the Electricity maps app, and use the code, it is similar to what is implemented currently, but not by country-region, but e.g. in America by ?provider? and one location of our table is not mapping to one region of electricity maps.
   2.1. The documentation needs to be adjusted and ElecticityMaps needs to be cited, attributed!
3. A hierarchical handling needs to be implemented to choose the appropriate locations ci: zone>country>world

Also I just realised, I implemented it, so that the CI is pulled right at the beginning of the pipeline run, it would be better to pull a new CI for each task actually, especially for longer pipeline runs! Downside -> the burden on ElectricityMaps server would be even greater! As not each pipeline run requests an CI but each task will request one!!
