Fix fread exception when length < 1 #66

Fixes this exception:

Uncaught exception in plugins/IP2Location/lib/IP2Location.php line 1602: fread(): Argument #2 ($length) must be greater than 0

I think the exception was thrown when processing a IPv6 address, but I am not 100% certain

May I know the BIN database you are using and the file's date?

Also, are you able to provide me with the IPv6 addresses that you suspect causing the error?

Hello @ip2location ,

here is my database version: Database Information IP2LOCATION-LITE-DB11.BIN IP2Location Database File 2022-03-29

I do not know the exact IPv6 address
