MudBlazor Extension for blazor-wasm-single-spa

Experimental extension for blazor-wasm-single-spa
that provides micro-frontend support of MudBlazor. This works by clearing and restoring global state
MudBlazor adds to the global window object when it is first initialized. The clearing and restoring
occurs when a Blazor WASM micro-frontend unmounted and mounted, respectively, by single-spa.

Usage

``javascript
import singleSpaBlazor from 'blazor-wasm-single-spa';
import mudBlazorExtension from 'blazor-wasm-ext-mud-blazor';

export const { bootstrap, mount, unmount } = singleSpaBlazor({
// Typical configuration
appTagName: 'my-blazor-app',
assetBaseUrl: new URL('https://mysite.com/app/my-blazor-app/'),
navigationBaseUrl: new URL('https://mysite.com/blazor-app/'),
stylePaths: ['css/app.css', 'MyBlazorApp.Client.styles.css'],
additionalImportPaths: ['my-js-interop.js'],

// NEW: Adding MudBlazor app extension
appExtension: [mudBlazorExtension()],
});
