Incompatible with rust edition "2024"

[justbuchanan]

I generated a simple project from template with cargo generate esp-rs/esp-idf-template cargo and was able to use espflash's save-image feature without issue. However, if I change the rust edition in Cargo.toml to edition = "2024", I get this error message:

$ cargo espflash save-image --chip esp32c3 out.bin

Error: cargo_espflash::invalid_workspace

  × The current workspace is invalid, and could not be loaded
  help: Ensure that a valid `Cargo.toml` file is in the executing directory

It would be nice if the error message was a bit more specific here. While I reproduced this problem using a fresh project generated from template, I initially ran into it on an established project and spent a while trying to figure this out.

I'm using espflash version "3.3.0".

This has been fixed in the main branch already, and is due to an outdated cargo dependency. See #799 and #800 for details.

Guess I should have left the issue open, so while this is fixed I will live this issue open until we publish our next release for anybody who may run into this in the future.
