give old blocks new sounds

A lot of the new blocks added in 1.13 and beyond have their own unique sounds. Copper doesn't just sound like another iron block for example. I suggest adding a new sound for each type of block in the game. With this change, things like gold and iron blocks will be distinguishable by sound, which has the added benefit of assisting the visually impaired with what's going on.

This was already done in some extent for the Nether Update, since Netherack, Soul Sand, Netherbricks, and some other blocks got updated sounds. I'd really like to see this expanded!
