Convert IonPyDict to regular Python dict, so that it is compatible with dataframe library like pandas polars

[MacHu-GWU]

My company are using DynamoDB heavily and use DynamoDB export to convert a DynamoDB table into a bunch of parquet file. We want to parse the exported ion file and then convert it to polars dataframe. However, polars dataframe doesn't recognize IonPyDict.

As of version 0.12.0 you can control that using IonPyValueModel.STRUCT_AS_STD_DICT.

See https://github.com/amazon-ion/ion-python/blob/master/amazon/ion/simpleion.py#L208

For example:

load(f, single_value=False, parse_eagerly=False,
                           value_model=IonPyValueModel.STRUCT_AS_STD_DICT)

Feel free to reopen if this doesn't meet your needs or somehow doesn't work for you.
