Enhancement request: fn to add deps map to the classpath

I realise update-classpath! can be used to achieve this, but it would be handy to have a dedicated fn in the lambdaisland.classpath ns that took a "deps map" (i.e. just the :deps portion of a deps.edn file), and added any missing dependencies described there to the active REPL classpath.

In effect this would emulate what pomegranate does, but with direct support for tda's "deps map" format (as well as things like git/sha coordinates), rather than leiningen's style of coordinates.

In my use case I'm running a clj initiated REPL outside the context of a "project", so there's no deps.edn file present to watch for changes. Instead, I want to try out different libraries by first finding them (e.g. using things like find-deps), downloading them from within the REPL, (requireing them, and then discovering and experimenting with their features. Only afterwards might a deps.edn file come out of that work.

Bắt đầu với update-classpath! trong src/lambdaisland/classpath.clj quanh dòng 263, sau đó lần theo cách xử lý dependency và classpath hiện có. Kết quả được yêu cầu là một public function trong namespace lambdaisland.classpath, nhận một :deps map của deps.edn, hỗ trợ các dạng coordinate đã mô tả và thêm các dependency còn thiếu vào classpath của REPL đang hoạt động.
