Makes RJ codes more useful.(8-bit RJCode supported.)
Verze ze dne
最近DLsite的RJ号从6位扩充至8位，由于未找到该脚本原作者的维护，故自己更新了8位RJ号的支持。
后续维护不保证，但有bug可以说。
本人非原作者，如果后续遇到版权纠纷将立即删除。
Description translated by translation software
Recently, the RJ number of DLsite has been expanded from 6 digits to 8 digits. As the original author of the script has not been found for maintenance, I have updated the support for 8-digit RJ numbers myself.
Further maintenance is not guaranteed, but bugs can be reported.
I am not the original author and will delete it immediately if there are any copyright disputes in the future.
基于原作者2.0.0版本开发，支持多语言 Based on the original version 2.0.0. Multi-Language Supported.
