Typescript compiler fails when using react css themr with error Default export of the module has or is using private name 'TReactCSSThemrTheme'

Typescript Version : 2.4.2
React CSS Themr: 2.1.2

**Replication Steps**

1. Create a component that uses themr.
`themr('Identifier')(ComponentName);`
2. Run the Typescript compiler

It will throw the following error
` error TS4082: Default export of the module has or is using private name 'TReactCSSThemrTheme'.`
` error TS4082: Default export of the module has or is using private name 'ThemedComponentClass'.
`

Reproduce the reported TS4082 errors with TypeScript 2.4.2 and React CSS Themr 2.1.2 using the themr('Identifier')(ComponentName) example. Trace the public exports involving TReactCSSThemrTheme and ThemedComponentClass; the issue is done when the compiler no longer reports private-name errors.
