Update algorithm benchmark

Thanks for this great work! I noticed the current [benchmark result](https://github.com/andrewssobral/bgslibrary/wiki/Algorithms-benchmark) is kind of outdated, could you please update that to the latest (with all available algorithms)?

增加对GDB命令“set trace-buffer-size”的支持

1

_KGTP_还不支持通过_GDB_命令`set trace-buffer-size`设置_ring buffer_大小，对这个命令的介绍在 [这里](https://sourceware.org/gdb/current/onlinedocs/gdb/Starting-and-Stopping-Trace-Experiments.html)。而和这个命令相关的_GDBRSP_包是`QTBuffer:size:size`，具体介绍在[这里](https://sourceware.org/gdb/current/onlinedocs/gdb/Tracepoint-Packets.html)。 具体实现可以在_KGTP_接到数据包后，分配一套新的_ring buffer_，之后把现有_ring buffer_中的数据拷贝到新的_ring buffer_中，然后释放现有_ring buffer_。 其中要注意的问题主要是如果现有_ring buffer_比新_ring buffer_大，需要丢弃一部分数据，如果被丢弃的数据正在现在_tfind_的范围内，可能需要一些特殊的处理。 最后如果实在不能在复杂的情况下比如_ring buffer_中有数据或者_tracepoint_运行中处理`set trace-buffer-size`，则允许_KGTP_报错。
