Chore updates and accept custom `<H3 />` component, breaking: removed child `<span />` components.

• Package updates
• Can now accept H3 component constant to modify static render only views in src/components/vignettes/Reader.js
• Removes children <span/> wrappers. This is the breaking change. This should help with bloated HTML in long documents but can break CSS styles.

Chore: Update dependencies

Applied dependency patches.

Fix peer dependencies

React 16 and 17 is now supported.

Chore: upgrades

Upgraded key dependencies for best speed/security

`lscache`

This project now uses lscache that helps with serializing/deserializing JSON data and is also able to free up space if there are other entries present in localStorage written with lscache with expiration.

This is a major version update because french-press-editor won't be able to read the previously saved content on your user's browsers since the localStorage keys have changed. You may want to migrate your keys as follows:

• "composer-content-text" to "lscache-composer-content-text"
• "composer-content-state" to "lscache-composer-content-state"

Anchored Headings

• All headings now have an id so that they could be linked to using anchor tags
• Dependency upgrades

Breaking

You will now have to rewrite plugins that use slate-react to use slate-react-legacy to be compatible with the upgrades to the stable legacy code. If you aren't using incompatible plugins, this should be a safe upgrade.

Note that this package also relies on styled-components@5
