feat: add support for map target type in Parquet options

[sclmn]

The map target type creates a schema without the added key_value repeated field.

Thank you @sclmn for adding the new fields for us! We usually require 100% test coverage. Could you please also add unit tests for the new properties, similar to unit tests here? We also require the first commit and PR title to follow conventional commits. Could you follow the instruction in the link to update your PR? If you need any help with these, feel free to let us know :)
