[FEATURE] import topology to pgm-ds arrays from dictonary of pgm ComponentType

[Bramtimm]

Considering I have a topology from power-grid-model in a dictionary, as from the power-grid-model-example below, I would like to have a simple interface/function to convert this to pgm-ds array objects. This would simplify the process of importing pgm topologies into pgm-ds.

Given the example below, the function should convert it to a dictionary of pgm-ds array objects. Optionally also supporting extension arrays if users have their own array objects.

I am happy to contribute to the implementation if needed.

from power_grid_model import ComponentType
from power_grid_model_ds import NodeArray, LineArray, LinkArray, TransformerArray, SourceArray

# PGM-topology
input_data = {
    ComponentType.node: node,
    ComponentType.line: line,
    ComponentType.sym_load: sym_load,
    ComponentType.source: source,
}

topology_pgm_ds = pgm_2_pgm_ds_converter(input_data, ...)

# PGM-DS topology
topology_pgm_ds = {
    "node": NodeArray,
    "line": LineArray,
    "link": LinkArray,
    "transformer": TransformerArray,
    "source":  SourceArray,
}

Sounds good to me. I think we want to switch to the ComponentType setup anyways. We can add a conversion method to the PGMInterface class

I agree with that it is a good feature to have. It makes integrating with the pgm-io conversion output easier as well. The design idea for adding it to the exesiting PGMInterface class is a good choice
