[WIP] Better fields filtering in encoders

[efirs]

Currently output schema can only less fields than input schema, meaning we can only filter fields from input schema. If it happens that input schema has less fields, for example, column is dropped in the source table, then it'll brake ingestion.

The idea behind this diff is to make filtering more generic and allow to filter both input and output schema columns.
