[dry-transformer] WDYTA adding ".map" to the HashTransformations-module?

Hey,

I think of something like this:

module Dry
  module Transformer
    module HashTransformations
      def self.map(source_hash, fn)
        source_hash.map { |key, value| fn.call(key, value) }.to_h
      end
    end
  end
end

to achieve following:

transformation = Dry::Transformer::Recursion
  .t(:recursion, Dry::Transformer::Conditional
    .t(:is, ::Hash, Dry::Transformer::HashTransformations
      .t(:map, ->(key, value) { [:time_from, :time_until].include?(key) ? [key, Time.parse(value)] : [key, value] })))

transformation.call({
  id: 1,
  address: { street: "Schulstrasse", zip_code: "6555" },
  from: "2023-02-09T09:03:06.144+00:00",
  until: "2023-02-10T09:03:06.144+00:00",
})
# {
#  id: 1,
#  address: { street: "Schulstrasse", zip_code: "6555" },
#  from: 2023-02-09 10:03:06.144899502 +0100,
#  until: 2023-02-10 10:03:06.144899502 +0100,
# }

I had this use-case and could not find a solution with the built-in transformations

Thanks
