Cover Geometry with H3 Cells and return a List of Long type cell IDs

SQL reference: [`ST_H3CellIDs`](/reference/wherobots-db/geometry-data/spatial-indexing/ST_H3CellIDs)

## Signature

```python theme={"system"}
from sedona.spark.sql.st_functions import ST_H3CellIDs

ST_H3CellIDs(
    geometry: ColumnOrName,
    level: Union[ColumnOrName, int],
    full_cover: Union[ColumnOrName, bool],
) -> Column
```

## Parameters

<ParamField path="geometry" type="ColumnOrName" required>
  Geometry column to generate cell IDs
</ParamField>

<ParamField path="level" type="Union[ColumnOrName, int]" required>
  value between 1 and 15, controls the size of the cells used for coverage. With a bigger level, the cells will be smaller, the coverage will be more accurate, but the result size will be exponentially increasing.
</ParamField>

<ParamField path="full_cover" type="Union[ColumnOrName, bool]" required>
  ColumnOrName
</ParamField>

## Returns

<ResponseField name="return" type="List[long]">
  List of cellIDs
</ResponseField>
