feat: drop lazy-object-proxy dep
Snakeoil DelayedInstantion is a superset of that in regards
to lieing to the python environment (making it a full thunk-
hiding it's even there). Snakeoil isn't as fast on the
implementation, but that's irrelevant for things like lazy-loading
subcmds which was the usage.
