Improve test coverage of command examples (#5650)

Browse Source 
* Ignore `cargo tarpaulin` output files

* Add expected result for `columns` example

Examples without provided expected output will never be tested.
The subset of commands available in `test_examples()` is limited thus
excluding the tests depending on other commands

* Add example test harness to `reject`

* Test and fix `wrap` example

* Test and fix `drop column` example

* Update `from ods` examples

* Update `from xlsx` examples

* Run `to nuon` examples

* Run `hash base64` examples

* Add example output to `path parse`

* Test and fix the `grid` examples
