Refactor break blocks to use calculated mining time

[nathanruiz]

I've added basic support for breaking blocks. At the moment, it can calculate the time required to mine each block for each tool with these exceptions:

• Using swords: Cobwebs, cocoa, leaves, melons, pumpkins, vines
• Using shears: Cobwebs, wool, leaves, vines

As part of this, I moved some of the existing code from Server into an ECS system to make it easier to maintain.

Looks like you have to apply cargofmt to make CI pass

@terrarier2111 I've run the formatter, checks are passing now.

Other than the network thingy this change looks great, thank you!
