Cannot pass rtol in latest version

[astrojuanlu]

In numbakit-ode 0.3 I could do this:

In [4]: import numpy as np

In [5]: >>> import nbkode
   ...: >>> def func(t, y):
   ...: ...     return -0.1 * y
   ...: >>> t0 = 0.
   ...: >>> y0 = np.array([1.])
   ...: >>> solver = nbkode.DOP853(func, t0, y0, rtol=1e-3)
   ...: >>> ts, ys = solver.run([0., 5., 10.])

In [6]: ys
Out[6]: 
array([[1.        ],
       [0.66453789],
       [0.52767336]])

But in 0.4, I get an error:

In [1]: import numpy as np

In [2]: >>> import nbkode
   ...: >>> def func(t, y):
   ...: ...     return -0.1 * y
   ...: >>> t0 = 0.
   ...: >>> y0 = np.array([1.])
   ...: >>> solver = nbkode.DOP853(func, t0, y0, rtol=1e-3)
   ...: >>> ts, ys = solver.run([0., 5., 10.])

This was fixed in 2c3b0c03a787615076316351f8417d58e73af40b

Thanks! Sorry for the noise, I'll have a look at the main branch before reporting next time
