Unexpected cfg condition value warning: vsda

[HomeDev68]

I encountered a warning related to an unexpected cfg condition value in the file src/tunnels/challenge.rs. The Rust compiler flagged the following:

warning: unexpected `cfg` condition value: `vsda`
 --> src/tunnels/challenge.rs:6:11
  |
6 | #[cfg(not(feature = "vsda"))]
  |           ^^^^^^^^^^^^^^^^
  |
  = note: expected values for `feature` are: `default` and `vscode-encrypt`
  = help: consider adding `vsda` as a feature in `Cargo.toml`
  = note: see <https://doc.rust-lang.org/nightly/rustc/check-cfg/cargo-specifics.html> for more information about checking conditional configuration

Is vsda a needed feature or should it be removed?
