Allow lazy options and arguments to reference parameters from groups, and allow unlimited recursion.
The way we support parameters referencing other parameters is by collecting any parameters that
failed to finalize and finalizing them again after all other parameters have succeeded.
Prior to this PR, we finalized options, groups, and arguments in separate passes. These passes were
interleaved and carefully ordered to work correctly.
This PR does away with the manual pass ordering and instead finalizes all parameters repeatedly,
iterating until a fixed point is reached.
Fixes #473
