Test fails with latest Rust

[yanganto]

Hi there,
Thanks for this crate.

The test fails with Rust 1.81.0 and the latest fitsdk (b0a639f98d450773e9c94dd42acf31c2da17e6aa)

failures:
    it_reads_all_files
    it_reads_wahoo_elemnt_dev_fields

test result: FAILED. 6 passed; 2 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.49s

I am not a cyclist but a Garmin G1 solar user and a diver, I want to build a side project with the .fit with diving logs.

There will be many more additional fields parsing for diving, and I will be happy to maintain this crate for a while. Can you add me as a co-owner to fitsdk and fit in crate.io if you have no time on these issues?
