Macro for easily creating block classes

NOTE:

The Type enum must have a Block subtype like this: enum Type { ...., Block, } and the Message must have a None subtype like this: enum Message { ...., None, }

Example:

block! {
    actor_type: ActorType,
    actor_message: ActorMessage,
    blocks: {
        block {
            name: GrassBlock, // the name of the block
            path: "assets/spritesheet.png", // the path of the spritesheet
            index: 20, // the sprite index inside the spritesheet
            width: 5, // width of block
            height: 5, // height of block
            sprites_in_row: 10, // number of blocks in the spritesheet in a row
            size: 20, // size of the rendered block
        }

        block {
            ....
        }
    }
}
