Turn a list of urls into a sitemap xml.
Options:
  --help                 Print this text
  --version              Print the version
  --validate             Ensure the passed in file is conforms to the sitemap spec
  --index                Create an index and stream that out. Writes out sitemaps along the way.
  --index-base-url       Base url the sitemaps will be hosted eg. https://example.com/sitemaps/
  --limit=45000          Set a custom limit to the items per sitemap
  --parse                Parse fed xml and spit out config
  --prepend=sitemap.xml  Prepend the streamed in sitemap configs to sitemap.xml
  --gzip                 Compress output
  --single-line-json     When used with parse, it spits out each entry as json rather than the whole json.

# examples

Generate a sitemap index file as well as sitemaps
  npx sitemap --gzip --index --index-base-url https://example.com/path/to/sitemaps/ < listofurls.txt > sitemap-index.xml.gz

Add to a sitemap
  npx sitemap --prepend sitemap.xml < listofurls.json

Turn an existing sitemap into configuration understood by the sitemap library
  npx sitemap --parse sitemap.xml

Use XMLLib to validate your sitemap (requires xmllib)
  npx sitemap --validate sitemap.xml
