pluggable dice engines

• Take one or two of the existing issues as an example. => Feature Request: Vampire The Masquerade 5th Edition #140.
• Try mirroring the wasmtime.rs.
• See if https://mbebenita.github.io/WasmExplorer/ can be used as a compiler. => WasmExplorer imports $malloc from the environment instead of using the grow instruction and managing the heap. I'd like to start with a clean webassembly instead, such as the one generated by Rust. AssemblyScript can allocate the memory as well and examining the code in https://webassembly.studio/ seems to confirm that, though it seems limited to the default memory size.
• Figure out ways to enhance the engine with extra code and maybe without reinventing everything from scratch.

• Try linking with https://docs.rs/wasmi/*/wasmi/.
• Try interpreting a Rust-generated webassembly in WASMI.
• Implement a working "hello world" stub of a GAE PDE and OSS it here
• Use case: allow PDEs to render images: PDE emits SVG, we pass it through resvg, including the resulting image in the bot's reply.
• External resources, Pick a random Steam game? #178.
