Wrangler: cleanse-column-names directive requires a trailing space

Description

When I use cleanse-column-names without a trailing space, the CLI adds a space after the directive, but nothing happens. The columns don't change and there's no error message. If I add a trailing space after cleanse-column-names, the directive works.

Seems like a bug to require a space after a directive that doesn't have arguments.

Wrangler does not convert String to Integer when 30% (or more) of the column's data is null. Steps to reproduce: 1) Upload the attached .csv file using Wrangler. Notice that all the fields are of type String 2) Go to Column transformations at the column NumericValue60 (which is made up of 40% null values), change the data type to Integer 3) The console won't display any error but the column will be shown as String The backend response has a "success" message but does not change the type of the column NumericValue60 to Integer.    Compare to following steps 2-3 for NumericValue70, which successfully changes the type to Integer.

The zeros as decimal places will still be shown. In addition, following these steps and trying to convert to Integer, an error message will pop up. The steps to reproduce are below: 1) Select column transformation at column NumericValues100 2) Convert to Float. So, the decimal zeros are shown 3) Convert to String. The decimal zeros are still shown, even thought the data type is changed. 4) Convert to Integer. An error will get returned from the backend.
