Creates `target/doc` in the wrong directory

[dpc]

When used in in a sub-crate of a larger workspace, when running cargo test a file is created:

./<sub-crate-dir>/target/doc/mermaid.min.js

instead of expected ./target/doc/mermaid.min.js for the whole workspace.

Seems to be caused by: https://github.com/mersinvald/aquamarine/blob/636675ba342a37a2a0aa87eb9adeea5c266f505c/src/attrs.rs#L140

Possibly CARGO_TARGET_DIR should be used instead as per https://doc.rust-lang.org/cargo/reference/environment-variables.html ?

thanks for filing the issue. You are right "cargo test" should not generate the file target/doc/mermaid.min.js.

In fact the file should be created only and only if invoking "cargo doc"

No file should be created invoking "cargo test" as the tests do not require the JS package.

Fixing this issue https://github.com/mersinvald/aquamarine/pull/36/commits

• extract into target/doc/MERMAID_FILE only if target/doc exists (created when calling "cargo doc")
• do not extract if target/doc/MERMAID_FILE already exists

has been fixed in newly released version 0.3.1 https://crates.io/crates/aquamarine/0.3.1
