v1.10.0

Features

• Added support for dev-libs attribute. (#8)

The dev-libs attribute indicates that you prefer using development versions of third party libraries
like react when the import-map-overrides ui is active. The presence of that attribute turns on this feature.
For example, if you have react in your import map pointing to https://cdn.jsdelivr.net/npm/react/umd/react.production.min.js
the dev-libs attribute will automatically override it to https://cdn.jsdelivr.net/npm/react/umd/react.development.js.
