remove usage of getrandom in rand dependency and in our crate

- 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

- bump versions
