Use Karl Seguin's http.zig as HTTP server backend: https://github.com/karlseguin/http.zig Update loggers to use new `jetzig.loggers.LogQueue` to offload logging to a background thread. Numerous other optimizations to remove unneeded allocs. Performance jump on a simple request from approx. 2k requests/second to approx. 40k requests/second (Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz). Color support for Windows Zmpl partial arg type coercion
