Error in gen_hard_bbox_rnet_onet.py

[jurastm]

Hello Bob, thank you for such nice code. your repo is much cleaner than other versions. Hovewer, I found one tiny error in gen_hard_bbox_rnet_onet.py in line 191: minFace = 24

For ONet stage minFace valuer should be 48 I think. If use 24 it fails to generate tfrecords, cause a lot of jpg files don't exist in data/onet folder. training also become meaningless with this setting.

I've changed minFace value to 48 and this solved this problem.
