The tools writebe64 and readbe64 depends on Lua, but Lua is not bundled

[mpolitzer]

The writebe64 and readbe64 tools depends on Lua, and the tools repository does not bundle Lua. Using them will give an error in distributions without Lua installed. We have to come up with a solution, maybe rewrite the tool in C or Rust? Or bundle Lua? Or can we live without these tools?

Lua is already present on the filesystem https://github.com/cartesi/machine-emulator-tools/blob/main/fs/Dockerfile#L45

Lua is already present on the filesystem

But not a dependency of the tools.deb yet, people are installing the tools on their own and not following our Dockerfile and having broken stuff, like the busybox issue in #43

I think we should get rid of needing Lua on tools, and do like Diego did with the hex tool that is made in C++.
