feat: Analyse different strategies and add validation for missing fields in parquet data compared to protobuf schema

[Meghajit]

Extra fields present in the parquet data not present in the protobuf schema will be ignored. However, it might be possible that:

• there are some fields in protobuf schema which are missing in the parquet data
• field names are same but the data type is different

We would need answers to as well as solve for :

1. Should the Parquet Data Source set default values for fields which are not found in the parquet file but present in the schema ? If yes, what should be the default value ?
2. If no defaults are wanted to be set, should the Dagger job fail ?

Removing this from Support for Parquet Files as a Source Milestone as it is a nice to have for the first milestone cc: @prakharmathur82
