    Description

      Currently if one tries to serialize an array or hash to bson which contains values that are not serializable, they get a less than informative exception:

      irb(main):006:0> [1..4].to_bson
      Traceback (most recent call last):
              6: from /home/w/.rbenv/versions/2.7/bin/irb:23:in `<main>'
              5: from /home/w/.rbenv/versions/2.7/bin/irb:23:in `load'
              4: from /home/w/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/irb-1.2.3/exe/irb:11:in `<top (required)>'
              3: from (irb):6
              2: from /home/w/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/bson-4.9.3/lib/bson/array.rb:45:in `to_bson'
              1: from /home/w/.rbenv/versions/2.7.1/lib/ruby/gems/2.7.0/gems/bson-4.9.3/lib/bson/array.rb:45:in `put_array'
      NoMethodError (undefined method `bson_type' for 1..4:Range)
      

      The exception should specifically state that an unserializable type is attempted to be serialized.
