remove rand dependency on getrandom package/feature

- we use rand internally to create random names for div's and for file
  names, for that reason highly performant crypto and/or efficinet
entropy generators are not a priority. Using rand with minimal features
and no `getrandom` simplifies usage for downstream users as they don't
need the custom WASM rustc flags for `getrandom` and `wasm_js` feature
