ann2rr: use data type int64 rather than int.

Benjamin Moody · Benjamin Moody · commit f25f92b39c14 · 2023-05-25T13:36:34.000-04:00
The alias 'np.int' has been removed from recent versions of numpy, and
there is no particular reason to want to use it here (as an array data
type, 'int' refers to a particular platform-dependent type, which is
not at all the same thing as an ordinary Python integer.)

Use int64 here for inter-platform consistency and to keep it simple.
