[PATCH] 5.0.1 Fix unmatched package.json version and published version

[COScholl]

• I ran npm version major after manually editing package.json with version 5.0.0, this bumped version to 6.0.0
• I then manually edited package.json again to 5.0.0
• I then ran npm publish, not realizing that this would cause a discrepancy with npm, where the stated version on https://www.npmjs.com/package/sane was '5.0.0', but npm install would list version in dependencies as 6.0.0

To correct, I ran npm version 5.0.1 and published, since you cannot republish an old version.
This may cause an issue with the next major version, and could require the next major version to start at 6.0.1
