Failing CI on master

[iqdecay]

After merging PR #49, CI isn't passing anymore.
Even though the PR CI was passing before merging.
Error in CI is:

failures:
---- call_with_structs stdout ----
thread 'call_with_structs' panicked at 'called `Result::unwrap()` on an `Err` value: CompilationError("Failed to compile core")', fuels-abigen-macro/tests/harness.rs:1028:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Unable to reproduce locally with cargo test call_with_structs

I'm re-running CI to see if it was just a transient issue.

Apparently this was due to a transient issue. And then to a disconnection because everything took so long. With the merge of FuelLabs/sway#688 that drastically reduces compile time, it should be solved.
A dependency issue fixed in #56 made CI fail but once it's merged it should go back to normal.
Edit: it did go back to normal!

[iqdecay]

Reopening because CI now fails, certainly because of some dependency updates.

This specific CI failure has been captured here #64. Closing this one.
