Added some benchmarking to show how fast it is:

Here is a benchmark comparing it to [Repomix][1] serializing the Next.js project:

      time yek
      Executed in    5.19 secs    fish           external
         usr time    2.85 secs   54.00 micros    2.85 secs
         sys time    6.31 secs  629.00 micros    6.31 secs



      time repomix
      Executed in   22.24 mins    fish           external
         usr time   21.99 mins    0.18 millis   21.99 mins
         sys time    0.23 mins    1.72 millis    0.23 mins

yek is 230x faster than repomix
