replace uses of numpy.long with int (#365)

Summary:
Pull Request resolved: #365

`numpy.long` is long deprecated and removed from numpy-1.24.0.

This replaces all uses with equivalent type `int`. Using the following oneliner:
```
fbgr '\bnp\.long\b' -lsf '.*\.py$' | xargs perl -pi -e 's,\bnp\.long\b,int,g'
```
