+Allows configuring oxidation stages, as a replacement for `WeatheringCopper#NEXT_BY_BLOCK` (which will be ignored in 1.21.2). This data map is also used to build a reverse deoxidation map (for scraping with an axe). It is located at `neoforge/data_maps/block/oxidizables.json` and its objects have the following structure:

+Custom blocks must implement `WeatheringCopperFullBlock` or `WeatheringCopper` and call `changeOverTime` in `randomTick` to oxidize naturally.
