More Supported Versions
In this update I have added support for some older versions! Now, the plugin supports 1.16.x - 1.18.x!

New Permissions
A permission has been added for each command:

• playerstatistics.playtime allows players to use /playtime
• playerstatistics.ping allows players to use /ping
• playerstatistics.stats allows people to use /stats
• playerstatistics.* controls access to all commands

All these permissions default to true.
