Fix object import

[linsword13]

Previously things like import ... as is not supported. Change to use importlib to support such standard access patterns.

Also unify the previous ObjectNamespace and RepositoryNamespace, into a single RambleNamespace.

Code Review

This pull request refactors module lazy-loading in ramble.repository by replacing ObjectNamespace and RepositoryNamespace with a unified RambleNamespace class, and switching from import to importlib.import_module. It also adds corresponding unit tests. The feedback highlights an issue where catching all ImportError exceptions and raising AttributeError masks nested import errors within the imported modules. It is recommended to only raise AttributeError if the ImportError matches the target submodule name, allowing other import errors to propagate.
