Feature Request: Option to download milkdrop preset in json format?

Hi, I have a preset I want to use but there's very few information on how to use your own presets. I don't mind trying to convert my own preset to json. The issue is that it's not clear how to use json milkdrop presets either.

Thank you!

Start by locating the existing Milkdrop preset loading flow and any UI for importing or exporting presets. Determine how JSON presets are currently represented and used, then define the expected download behavior and documentation; done means a user can obtain a JSON preset and understand how to use it.
