* CSC POC ontop of Parser * add csc file that weren't merged after patch * address review comments * nits to try and fix github * last change from review * Update client-side cache and improve documentation * Add client side caching RESP3 validation * Add documentation for RESP and unstableResp3 options * Add comprehensive cache statistics The `CacheStats` class provides detailed metrics like hit/miss counts, load success/failure counts, total load time, and eviction counts. It also offers derived metrics such as hit/miss rates, load failure rate, and average load penalty. The design is inspired by Caffeine. `BasicClientSideCache` now uses a `StatsCounter` to accumulate these statistics, exposed via a new `stats()` method. The previous `cacheHits()` and `cacheMisses()` methods have been removed. A `recordStats` option (default: true) in `ClientSideCacheConfig` allows disabling statistics collection. --------- Co-authored-by: Shaya Potter <shaya@redislabs.com>
