numpy 1.24.0 np.bool removed needs cleanup

[TAlonglong]

With numpy 1.24.0 ( as far as I understand) np.bool ( and others) are removed.

This needs to be cleaned up.

np.float too. I see one use of both:

pytroll-schedule/trollsched/graph.py

Lines 34 to 35 in c765fb0

	self.adj_matrix = np.zeros((self.order, self.order), np.bool)
	self.weight_matrix = np.zeros((self.order, self.order), np.float)

Hopefully I can get this fixed in #72
