1：Solve the problem of buffer overflow when PCAP data is large;

2：Thread locks and condition variables are used to balance push and POP.

3：Based on the@iurii-provizio Work to develop and to 909a3bc#diff-66 ae3288ae851a5f0eb11df04565dd2c9de744f85221e3dc9870e1537e046a9e

about issues:

• PacketsBuffer_s is thread unsafe though used in different threads without any mutexes #22
• "buffer don't have enough space" - hasEnoughPackets() function #19
• buffer don't have space #17

@anchuanxu seems reasonable, but there is no finish condition: in case something waits for a conditional variable, we can't destroy (and can't finish the parent app f.e.).

我想在HesaiLidar_General_ROS这个工程里面使用，但是您所改的文件是SDK中的。然而 HesaiLidar_General_ROS里面的SDK文件夹与这个单独的SDK不一样，直接进行替换似乎不行。我该如何解决这个问题呢
