HomeyScript to parse an integer from any argument type within a flow. The result is provided in the `value` tag. You can optionally set a different output type: `number` (default), `string` or `bool`.

/**
 * Parse the argument to an integer of `number` type.
 * Optionally you can enforce the output type to `number` (default), `string` or `bool`.
 * The result is provided in the `value` tag.
 *
 * @example  '22:00'        -> 22
 * @example  '22:00 string' -> '22'
 * @example  '22:00 bool'   -> true
 * @example  '0 bool'       -> false
