clippy: fix multiple issues

[micolous]

Fixes multiple clippy failures in CI:

• (error) derivable_impls for many Default implementations (added in new clippy)
• (error) expect_used regressions missed in making a basic test for a webauthn object from a chrome extension #289
• (error) mismatched image library versions from bardecoder
• (warning) wrong_self_convention in Eid::to_bytes()
• (warning) bool_assert_comparison in nfc/atr.rs tests
• (warning) box_default in multiple places

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

That's ... a lot of CI failures O_O

I missed two issues which #294 got; I've cherry-picked the extra fixes in b7b9ab9 onto my branch as 4fa07ac.

Remaining clippy failures appear to be regressions introduced in e9ebff3 (#289), where the existing CI failures stopped clippy checking webauthn-rs where these new failures were present:

These are both used in a test.

There ended up being more clippy failures than just that, but I believe this is all in order now.
