lightning-0.0.104 fails to compile on Rust 1.60 beta due to ambiguous `fmt` call in `ln/msgs.rs`

[the8472]

A crater run found that the crate no longer compiles on Rust 1.60 beta (see rust-lang/rust#94507) due to a newly added trait impl in the standard library causes ambiguities in method resolution.

The regression has been deemed an acceptable minor change per RFC 1105.
It can be fixed by using fully qualified function call syntax to disambiguate the fmt call.

Yes, we tried to open an issue upstream at rust-lang/rust#93599 and report it some time ago, see discussion there.

Hah, I even commented there. Sorry for the noise as you already were aware.

All good, not your job to map names to projects.
