ascent_macro: Fix minimal versions (by upgrading syn to v1.0.109, itertools to v0.12) about ascent HOT 5 CLOSED

Thanks @regexident for catching the issue. I'll try and make the suggested fix as soon as possible.

Looks like there is some pending effort on this here (#18). I am not sure what the resolution is right now, however.

#18, which I linked in OP, is about a possible migration to a future syn 2.x.

This issue is specifically about semver breakage that's happening today when depending on both, ascent v0.5.0, due to the dependencies in ascent's Cargo.toml using versions that don't yet contain features used by ascent. See "Full terminal log" for how to reproduce and what's broken.

Understood. I will try to look into this and get back to you. Arash has now graduated, I am not sure the degree to which he will maintain the repo in real-time since he's now got a full-time job. In that event, we can look into forking the repo into a version our group maintains. I will try to get back to you in the next weeek.

Thanks @kmicinski!

I'm currently experimenting with migrating cargo-modules's custom-written and rather unwieldy recursive graph/tree filtering transformations towards individual and composable transformation phases consisting of succinct Datalog programs using ascent.

I currently have to pin these two dependencies in my project's own Cargo.toml to make things compile.

I'm not an experienced in Datalog implementations/theory (beyond having read a couple of articles and lectures), but would be happy to help maintain the Rust side of things if there is need for additional hands.
