Fix compilation and update dependencies

[DeimosHall]

Hey, I just fix the following issue by updating the dependencies of the project:

warning: no edition set: defaulting to the 2015 edition while the latest is 2024
    Updating crates.io index
error: failed to select a version for the requirement `security-framework = "^0.1.13"`
  version 0.1.13 is yanked
  version 0.1.14 is yanked
  version 0.1.15 is yanked
  version 0.1.16 is yanked
location searched: crates.io index
required by package `native-tls v0.1.3`
    ... which satisfies dependency `native-tls = "^0.1.3"` of package `reqwest v0.8.5`
    ... which satisfies dependency `reqwest = "^0.8.5"` of package `dlc-decrypter v0.2.1

I also added tokio to have async capabilities, if you disagree, please let me know.

By the way, the readme isn't displayed on crates.io, but idk why.

Hey people, for anyone interested on this project I'll continue working on it on my own fork: https://github.com/DeimosHall/dlc-decoder
