Upgrade proc-macro-crate

[jplatte]

You didn't declare an MSRV, so publishing a new version with this in as a patch release should be fine.

I will upgrade the syn to 2.0 and then publish a new version. Maybe I would add some check on CI and rewrite unit tests if I have time.

[jplatte]

Oh, somehow I missed that syn is also due for an upgrade (not at 2.0 yet here) 😄

Hey @TOETOE55, any reason this PR isn't merged? Do you need help with the syn upgrade?

#5 Here are some of the status quo of cfg-vis, some issues have not been thought through, so you have been shelving your PR.

(On the other hand, I may not have much energy or time to work on open source projects for the next year or two.)

Thanks for the update! I'm not super happy with having conditionally-public items anyways, so maybe I'll try to remove the cfg-vis use altogether.

I'm sorry~. I'll also try to find out if anyone can help.

No worries, you don't owe me or the other users of the library anything :)
