- remove -o/--oneunit, has been the default behavior
- revise test coverage for default vs. siloed behavior
- add test to ensure README usage matches CLI help text
- remove -V alias for --version
- remove -? alias for --help

- wait for hierarchical references within an instance's type parameters
  to be resolved before instantiating the module
- references to a module's top-level named scopes are now correctly
  renamed when creating new type parameter modules

- delegate cast type and sign resolution to TypeOf conversion
- internal support for injecting data declarations into statements
- fix size and sign of unbased unsized literals used in casts
- avoid generating many unnecessary explicit casts
- support casts which depend on localparams within procedures
- expression traversal correctly visits types within type casts
- fix typeof on expressions of net types
- handle additional edge cases for unsized integer array patterns
- preserve signedness of implicitly flattened unpacked integer arrays

- warnings were skipped because verbose about was technically not empty
- add test suite for these warnings in both modes

- split out typeof handling of part selects
- account for directionality of base dimension
- refactor dimensions test case with detailed output
