The error named the internal type System.Nullable`1[System.Int32]. Use a custom parser that reports 'Option ... requires a whole number'. Related to #1.

Summary
Since 2.0.0 an invalid
--max-countvalue is an error (see #1), but the message named the internal type:Both integer options (
--max-count,--offset-width) now use a shared custom parser:Exit code stays
1, the message goes to stderr. The--offset-widthdefault (6) is now documented in its help text instead of the generated[default: 6].This does not close #1 on purpose, that is up to the release of 2.0.0.
Test plan
dotnet test: 32/32 (new: non-numeric--max-count,-m,--offset-width, offset column width)abcfor both options
