Updated ProxyData exceptions to include previous exception to finish stacktrace

Updated LiveUserData.Request to throw an IllegalArgumentException when a null or blank username is provided
Updated HttpClientSettings to use setProxyClientSettings instead of direct access
Fixed ProxyRotation bug starting at index 1 instead of 0 and made methods default to synchronized in case concurrency is used in implementors code
Changed HttpClient#toUrl to toUri
Added @Getter to HttpClientFactory for liveClientSettings
Added consumer to TikTokLive#requests so that way proxies can be used when calling the fetch methods
Changed LiveUserData.Response#startTime to clarify the variable name
