Zachary Snow 84edbae503 preliminary scoped errors with approximate source location
- scoped traversals can now raise errors which contain the path of the
  current scope and an approximate source location based on preceding
  trace comments, if available
- initially, this new error messaging has only been added for the
  illegal size cast checks in the TypeOf and Cast conversions
- error suite tests can provide a verbose mode expected source location

Zachary Snow 40f66e0212 add type signatures for all parser rules
This works around a compilation performance regression in GHC 9.0.1:

compilation on other versions.

Zachary Snow 306d71334b refactor sizing and truncation of integer literals
- use iverilog's -gstrict-expr-width throughout test suite
- add warnings for excess bits or padding zeroes in number literals
- add new --oversized-numbers parameter to retain support for unsized
  numbers wider than 32 bits
- localized use of oversized numbers to new truncate test suite which
  verifies the behavior of both modes, and compares against the known
  behavior of iverilog
