v1.21.0 - Optimize local mode initialization

Introduced 2 new options to configure the load strategy of the IP to country lookup & UA parser.

• IPCountryOptions
  • Disabled: Fully disable IP to country lookup
  • LazyLoad: Load in background
  • EnsureLoaded: Wait until loaded when needed
• UAParserOptions
  • Disabled: Fully disable UA parser
  • LazyLoad: Load in background
  • EnsureLoaded: Wait until loaded when needed

These are 2 of the more expensive processes during initialization of the SDK outside of network requests.

• If your service does not rely on country based checks from an IP address, disabling IPCountry is recommended.
• If your service does not rely on parsing the UserAgent, disabling UAParser is recommended.
• LazyLoad is generally recommended to avoid waiting to initialize these on start up. EnsureLoaded will ensure that it's loaded when eventually needed for evaluation.

Bug fix:

• Disable internal error logging in Local Mode

• 3b13ae3 kenny-statsig
