JSON type support about fluent-plugin-bigquery

[joker1007]

Perhaps, if you define a field in the table schema that uses JSON Type and send the JSON data to that field as a string, you can use it in the current plugin version.

It's currently throwing following error

I think need to explicitly add it to FIELD_TYPES.

I will create PR to add the support if you don't have any objection .

Thanks. I understand what this plugin needs.
I will fix the schema handling.
