* Add VariableTestContainer in ssz_query.proto * Add listInfo * Use errors.New for making an error with a static string literal * Add listInfo field when analyzing the List type * Persist the field order in the container * Add actualOffset and goFieldName at fieldInfo * Add PopulateFromValue function & update test runner * Handle slice of ssz object for marshalling * Add CalculateOffsetAndLength test * Add comments for better doc * Changelog :) * Apply reviews from Radek * Remove actualOffset and update offset field instead * Add Nested container of variable-sized for testing nested path * Fix offset adding logics: for variable-sized field, always add 4 instead of its fixed size * Fix multiple import issue --------- Co-authored-by: Radosław Kapka <rkapka@wp.pl>
