Upgrade hyper/http, use new APIs

[micolous]

Note: it compiles, but I need to test with physical hardware.

Upgrades http, http-body-util and hyper to current versions.

hyper switched from using Tokio traits to their own custom traits a while ago, but have an adapter to Tokio traits (hyper-util). So this switches everything to use the adapter.

• cargo test has been run and passes
• documentation has been updated with relevant examples (if relevant)

@micolous Given how much this PR is blocking I think we should merge it and commit to testing later.

I can't actually find all the hardware pieces I need to test this properly. 😞

cable-tunnel-server-* is mostly a proof-of-concept demo rather than anything intended for serious usage, so I'm less worried if something breaks.

CI was failing because fido-hid-rs has a transitive dependency on home, which as part of cargo, has an MSRV-3 policy (=1.81), which is higher than our MSRV (=1.79).

#461 bumps the MSRV to 1.81. I've included that patch in this PR as well to make the build pass.

If you're happy with that, we can merge #461 first, then this on top.

Seems legit to me, dependency has been merged as noted
