      Description

      Hi, I might find a bug.

      When we specify column type as time via Arrow::Table.load's column_types named argument, it causes segmentation fault:

      I think Ruby's any extension libraries should not cause SEGV.

      Script to reproduce this issue(timedata.rb):

      require "arrow"
      CSV_FILE = File.join(__dir__, "timedata.csv")
      table = Arrow::Table.load(CSV_FILE, column_types: [["datetime", :time]])

      Sample CSV file(timedata.csv) is:

      id,datetime,name
      1,2019-12-19T18:30,
      ,,
      

      Result:

      % ruby -v ./timedata.rb
