NumberInput: Initial value cannot be empty string due to PropTypes

What package(s) are you using?

• carbon-components
• carbon-components-react

Detailed description

PropTypes for both value and defaultValue are set to Number so you cannot have it's initial value as an empty string despite the allowEmpty property. The following is logged to the console:

Warning: Failed prop type: Invalid prop valueof typestring supplied to 'NumberInput', expected 'number'.
