Suggestion: support monorepos in module resolution

[Quantumplation]

I'd like to create a monorepo for multiple aiken libraries in it owned by SundaeSwap;

The ideal structure in my eyes is:

SundaeSwap-finance/aiken-libs
|- multisig/
|  |- aiken.toml
|  |- lib/
|  |  |- sundae/**
|- other-thing/
|  |- aiken.toml
|  |- lib/
|  |  |- sundae/**

And then I could add a dependency like this:

[[dependencies]]
name = "SundaeSwap-finance/aiken-libs/multisig"
version = "main"
source = "github"
