Unable to build latte on Ubuntu 22.04

[drednout]

Hello!

I tried to build latte from source using cargo and latest stable rust(1.73.0), however I received a build error:

$ cargo build
error[E0512]: cannot transmute between types of different sizes, or dependently-sized types
  --> /home/dr/.asdf/installs/rust/1.73.0/registry/src/index.crates.io-6f17d22bba15001f/rune-0.12.3/src/hash.rs:68:18

   = note: source type: `std::any::TypeId` (128 bits)
   = note: target type: `hash::Hash` (64 bits)

Could you fix the issue or suggest a workaround?

I can confirm I'm seeing the exact same failure

switching to rune 0.12.4, seems to fix the issue: https://github.com/rune-rs/rune/releases/tag/0.12.4

@fruch, big thanks! Now I can build latte from the main branch.
