Version 1.3 Changes:
Support 1.16.5 - 1.21.5 (JDK 21)

[Not working perfectly] Added particle stress test - /fb test particles <amount> allows testing server performance with large amounts of particles
Added chunk loading test - /fb test chunksload <seconds> simulates 4 players running in different directions to test chunk loading performance
[Not working perfectly] Added player simulation test - /fb test players <amount> <duration> simulates player connections and activity
Added system information command - /fb stats displays CPU info, frequency, manufacturer and SWAP memory
Added PlaceholderAPI support with placeholders:
%fastbenchmark_cpu_load% - current CPU load
%fastbenchmark_cpu_maxload% - maximum CPU load
%fastbenchmark_cpu_threads% - CPU thread count
%fastbenchmark_noderam_used% - used system RAM
%fastbenchmark_noderam_max% - maximum system RAM
%fastbenchmark_realram_used% - used process RAM
%fastbenchmark_realram_max% - maximum process RAM
%fastbenchmark_cpu_name% - CPU name
%fastbenchmark_cpu_manufacturer% - CPU manufacturer
%fastbenchmark_cpu_frequency% - CPU frequency
%fastbenchmark_cpu_swap_enabled% - SWAP enabled status
%fastbenchmark_cpu_swap_used% - used SWAP
%fastbenchmark_cpu_swap_max% - maximum SWAP
Added tests.yml configuration file for customizing all tests (completion sounds, spawn limits, chunk radius)
Improved compatibility - plugin now works without OSHI and PlaceholderAPI, disabling corresponding features
Added HEX colors and gradients to all messages for better visual appearance
Added error protection with try/catch blocks in all critical areas
Updated mob list for 1.16.5 compatibility
Added third help page for new commands
