Switching to a rust-native CIL emitting API

Hi! I saw this project on reddit and was very excited; I've been trying to accomplish this exact project before and stalled multiple times due to realizing the amount of work it would require and the potential for failure. However, I was halfway through writing an ECMA-335 compliant CIL ser/de (shorthand, not `serde`) library on my last attempt. Would you be interested in working together to port this compiler to my own CIL backend, to hopefully achieve better efficiency and maybe even better validation? Not to mention cutting out the need to invoke ILASM or any non-rust dependencies.

If not, I'd still like to contribute to the project, and might make periodic PRs to improve it in whatever ways I see. I likely won't have a lot of time to dedicate to it any time soon, but I might be able to work on it every now and then.
