[FEATURE] Serialize and Deserialize Grid to python dict

[TomInfiniot]

I want to save my grids as a json to a json column in a database and also retrieve these grids from the database and convert them back to a Grid instance. However the serialize method for a Grid currently serialized to a file and the deserialize method also takes a file path as input.

for saving
I would like to avoid the intermediate step of writing the grid to a file and then reading the file to a string that I can add to my insert query. Instead I would like a method to serialize the grid to a python dict that I can then directly use in my database API.

for retrieving
I would like to avoid the intermediate step of writing the json from my database to a file, before I can deserialize to a grid instance. I would like to be able to use a method that deserializes a pyhton dict to a Grid instance.

Hi @TomInfiniot ,

I will close this issue as a duplicate of #210. Feel free to add your wish there if needed.
But in general this is something we want to implement and I see that @jaapschoutenalliander already has a draft PR (#219) open for this feature. So hopefully we can finalize that implementation in the near future.
