[pdal] reading las is slower than liblas

[Luca Delucchi]

Hi devs,

I'm doing some comparison between liblas and pdal and it seems to me
that pdal is really slower to read las files.

Following the result of time command with the same las file:

- liblas
real    0m2.145s
user    0m2.072s
sys     0m0.068s

- pdal
real    0m48.900s
user    0m48.160s
sys     0m0.785s

do you have any idea why is so slower?

PS
I tested several files and it seems to me that the time of pdal is
equal ~20 time the result of liblas
