Possible gpcc output binary bug

run the test script.

sudo chmod 777 tmc3 pc_error_d
python coder.py --filedir='longdress_vox10_1300.ply' --ckptdir='ckpts/r3_0.10bpp.pth'
python test.py --filedir='longdress_vox10_1300.ply'

The latest version of tmc downloaded from https://github.com/MPEGGroup/mpeg-pcc-tmc13 outputs binary format ply instead of ascii format ply by default, but our program can only handle ascii ply, resulting in running errors. Set --outputBinaryPly=0 to solve.
