API to retrieve additional blocks and block information.

I believe we can utilise the https://github.com/PrismarineJS/minecraft-data project as a reference to provide further information for some straightforward determinations. For instance, when mining blocks, you can refer to the hardness in the block.json within the https://github.com/PrismarineJS/minecraft-data and the pertinent data in the materials.json.

I believe that implementing this feature will be very beneficial in creating mini-games and restoring the original mining settings of Minecraft. Naturally, there is more to it than that.

We prefer to extract metadata directly from the game using our extractor. Its a fabric mod that exports JSON that we in turn use to generate rust code with that data.

[Inotart]

My point is not to use data from other libraries, but to get more information at the time of extraction to help implement more functions, such as mining decisions.

Feel free to add a pr that changes what gets extracted in blocks.java. see here

I am not sure this is in the spirit of valence (we only need an amount of data that can be expressed in packets any further can be implemented by library users) aka if a field is explicitly server-side then the valence library shouldn't need to know of it. If on the other hand hardness could be affected by by packets to the client then this should absolutely be included.
