Skip to set string type

[koooge]

columns must be set type: string presently.
Although I want to allow columns can skip type attribute when its type is string, it causes a ConfigException Attribute type is required but not set now.

config.yml

type: csv_guessable
schema_file: path/to/file.csv
columns:
  - {value_name: 'id', name: 'number', type: string}
  - {value_name: 'title', name: 'description'}
  - {value_name: 'status', name: 'ok?'}

'type' column is needed by embulk-core.
I reconsidered this. I think this is a bit over the top.

org.embulk.exec.PartialExecutionException: org.embulk.config.ConfigException: com.fasterxml.jackson.databind.JsonMappingException: Instantiation of [simple type, class org.embulk.spi.ColumnConfig] value failed: Attribute type is required but not set
