release/0.28 audit failing due to RUSTSEC-2022-0046.html

[notmandatory]

Describe the bug

For some reason the CI audit just caught that there is an issue with rocksdb due to "Out-of-bounds read when opening multiple column families with TTL". See:

https://rustsec.org/advisories/RUSTSEC-2022-0046.html

To Reproduce

cargo update
cargo audit

Expected behavior

Should not fail audit tests.

Build environment

• BDK tag/commit: release/0.28
• OS+version: any
• Rust/Cargo version: ci tests against 1.57.0 and 1.65.0
• Rust/Cargo target: any

Additional context

The rocksdb dependency is only used when the compact_filters feature is enabled. The reason we haven't update our rocksdb version earlier is that newer versions don't support our MSRV of 1.57. See also #480.

I propose we disable the audit warning for this issue since compact_filters is an experimental feature and we don't use the rocksdb "multiple column families with TTL" feature mentioned in this advisory.
