When trying to write a parquet file with :decimal types, I receive the following error:

; Execution error at tech.v3.libs.parquet/column->field (parquet.clj:886).
; Unsupported datatype for parquet writing: :decimal

Is it possible to add support to write decimal type?

Yes for sure it is possible
