Write SPA fallback .htaccess

Generates a single .htaccess file that routes any non-file/non-dir request
to index.html, so Angular SPA client-side routes work when the app is
hosted under a subpath (e.g. wp-content/uploads/tsai/player/browser/).

Usage:
    python write_spa_htaccess.py <output_path> <base_href>

Example:
    python write_spa_htaccess.py /path/to/dist/scike/wp-shared/player/browser /wp-content/uploads/tsai/player/browser/
