Support batch get expriment.

[Hikkovo]

hi! can support a function to batch get expriment? like this
fun batchGetExperimentAsync( user: StatsigUser, experimentNameList: List<String>, ): CompletableFuture<List<DynamicConfig>> {}

Hello! Can you explain more about why you'd like this, instead of calling each in a list or loop?

For context, a call to getExperiment() does not spawn a network request, all evaluations are stored in memory after initialization. We don't plan to support this without more info on the user need, happy to reopen if needed 😄
