Don't transform modules with import/export #96
Had this issue with the recently released newest version of firstname.lastname@example.org (https://github.com/reactjs/redux/releases) which updated its symbol-observable dependency to version 1.0.2 (https://github.com/blesh/symbol-observable/blob/master/CHANGELOG.md) with es6 support.
A temporary fix is to simply ignore symbol-observable specifically as an exclude field in the commonjs plugin.
I just want to say that I tested this PR and it worked out of the box with the newest version of email@example.com and its updated symbol-observable dependency (and as a result fixed my build and dev npm scripts)
People using redux with the hat character ^ in their dependencies (like I did) will at some points auto update to 3.6.0 and come across this issue that this PR seems to fix.
The only there difference is that using this PR rollup-plugin-version logs out a message when running rollup/build script (not an error)
Other than that everything seems to be working the same.
