Completely rewrote value converters responsible for parsing integer literals as TypedBigInteger instances.
Apart from implementation details, these are the behavioral changes:
Verilog-style literals now support underscores to separate groups of digits
Signed Verilog-style literals now provide negative values when the sign bit is set
Verilog-style literals will now generate diagnostics if the value's bit pattern does not fit within the specified width
