getEurobisGrid, getEurobisPoints implement same variables as getEurobisData

[LennertSchepers]

currently the getEurobisGrid and getEurobisPoints only can have the Aphia (and grid size) as input, but it should be good to have the same possibilities as the getEurobisData function:

• geourl
• aphiaid
• speciesgroup
• mrgid
• startyear
• endyear
• type

and somewhere specify in the function/examples how they can retrieve from which datasets these data come from.

@salvafern you removed the eurobis grid/points functions from the package?

[salvafern]

Yes I removed the functions of the old package. It was a quick fix to make the package be more robust towards the EBR workshop. I can restore the old functions of even better, write new ones. But I wonder if the grid functions are that necessary. In my opinion these are useful only as a visualization tool - therefore we should rather visualize via WMS.

I'm not sure we can offer all the possibilities to query on. There are some limitations with this layer. Better to discuss internally.

To be continued in #22

As I said, the grid layers don't allow to query on all those filters. Only on dataset and aphiaid.
