Gaussian radius implementation is wrong

[fengenxiang1123]

Reference https://github.com/zzzxxxttt/pytorch_simple_CenterNet_45/issues/5 The original Gaussian radius implementation is should be updated!! For example,

delete r1 = (b1 + sq1) / 2 add # r1 = (b1 + sq1) / 2 # add r1 = (b1 - sq1) / (2 * a1)

How about the performance after you updated?

It should be carefully checked 🤔
