1.1.1 Fix TypeError in webpack3 cases

Remarkably simple oversight, I apologize whole-heartedly. That said, I spent more time trying to get a webpack3 build configuration to work at all for the test cases, and ultimately could not, due to many many many deprecated packages. As such, I made this fix just in case, but if at all possible, you should likely upgrade to webpack 4.

Webpack 5 support

1.1.0 Verify support for webpack v5 and html-webpack-plugin v5

• No changes needed, package.json updated to reflect current dependency versions

Include .d.ts declaration files in package

1.0.4 Include .d.ts declaration files in package

• Addresses #15
• Remove testcases with Webpack 3 (compatability issues with mini-css-extract-plugin)

Handle production-mode defaults of webpack

• Added documentation around a potential pitfall when using production-mode webpack.
• Upgraded test dependencies
• Fixed peerDependency version syntax

Don't remove non-links

Fixed an issue where non-links were being removed, rather than left alone.
