version 4.5.4

Minor bugfix release

• Fixes peaks not fading out in radial graph mode when fadePeaks enabled;
• Updated dev npm packages to address vulnerability reports;
• Updated the suggested CDN in the Usage section to jsDelivr, which can provide minified versions of both the ESM and UMD modules.

NOTE: If you're using this package from a CDN, make sure to pin the version to v4 (by adding @4 after the package name) to prevent breaking changes when stable v5 is released!
