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.

Beginne mit update-classpath! in src/lambdaisland/classpath.clj ungefähr bei Zeile 263 und verfolge anschließend die bestehende Behandlung von Abhängigkeiten und Classpath. Das gewünschte Ergebnis ist eine öffentliche Funktion im Namespace lambdaisland.classpath, die eine deps.edn :deps-Map akzeptiert, die beschriebenen Koordinatenformen unterstützt und fehlende Abhängigkeiten zum aktiven REPL-Classpath hinzufügt.
