NBMiner v39.0更新日志：
feature: ethash New LHR mode for ETH mining on RTX 30 series LHR GPUs, supports Windows & Linux, able to get ~70% of maximum unlocked hashrate.
This mode can be tuned by argument -lhr, only works for ethash right now.
-lhr default to 0, meaning even if -lhr is not set, LHR mode with -lhr 68 will be applied to LHR GPUs if certain GPUs are detected.
Tune LHR mode by setting -lhr , a specific value will tell miner try to reach value percent of maximum unlocker hashrate, e.g. -lhr 68 will expect to get 68% of hashrate for same model non-LHR GPU.
Higher -lhr value will results in higher hashrate, but has higher possibility to run into lock state, which will leads to much less hashrate.
A good start tuning value is 68, which has been tested to be stable on most rig configurations.
-lhr value can be set for each GPU by using comma separeted list, -lhr 65,68,0,-1, where -1 means turn off LHR mode.
Known issue
unable to unlock LHR hashrate under windows driver 471.11
===================================================
功能: ethash 新增部分破解 LHR 版本显卡算力的功能，适用于win和linux，大约可解锁70%左右的满速算力。
该功能通过-lhr参数启动，目前只对ethash算法有效
如果检测到有LHR显卡，即使不加-lhr参数时，也会自动对其使用 -lhr 68的参数应用。
其他非LHR显卡挖矿不受影响，3060 v1版本需要设置 -lhr 才启用 LHR 模式
可通过 -lhr 来手动指定，的值指尝试让miner达到的算力目标，比如 -lhr 68 即尝试让miner采用满算力（不带锁的卡）的68%的有效算力来运行，即越大算力越高。
-lhr 的数值越大，挖矿过程中被锁算力的概率越大，默认值 68 是开发测试中可以长期稳定运行的值，用户可以尝试调高或者调低该数值，以取得算力和稳定性的平衡
可通过 -lhr 65,68,0,-1 格式来单独指定每一张卡的参数，其中 -1指关闭 LHR 破解功能
已知问题
windows 471.11驱动，无法解锁LHR算力
