OverflowError when using random_state with Fock space

Created by: femtobit

This produces an OverflowError on my system:

import netket as nk

hi = nk.hilbert.Fock(N=1)
print(hi) # Fock(n_max=INT_MAX, N=1)

rng = nk.jax.PRNGSeq(0)
hi.random_state(next(seq))

OverflowError: Python int 9223372036854775808 too large to convert to int64

Note that 9223372036854775808 is hi.n_max + 1 so it appears to be an off-by-one error somewhere.
