build: ensure msrv 1.80.1 and upgrade dependencies

[tisonkun]

This refers to #8

Thanks!

I feel like it's too aggressive to have an MSRV like this. But we can see if it works well and evaluate it as needed.

[tisonkun]

The background is that, we don't actually define an MSRV before and it's effectively latest stable. Thus, use the current stable version is the least surprising one.

[tisonkun]

Also reducing MSRV should not be a breaking change IIUC.

[Xuanwo]

I'm fine with this policy.

Seems the same problem as #9 but on linux.

@andylokandy Then perhaps merge this one and debugging the macro issue later?

Yes, was just waiting for ci to rerun
