fix: parsing walltime results in cargo codspeed breaks backwards

[not-matthias]

Builds upon #99

Changes in this PR:

• Removed RawWalltimeData: We're now directly creating the WalltimeBenchmark struct
• Move the WalltimeBenchmark/WalltimeResults logic to codspeed crate. Also moved the logic for clearing / collecting the results in case we want to change the path later on (so we dont have to change it in cargo-codspeed as well)
