BaseCircuit.predict() won't take float as input

[Yugal0]

BaseCiruit.predict() only accepts a nd.array as an input,
hence the frequency data need to be compulsory supplied as an array
But If I want to predict the impedance at a particular frequency, then BaseCircuit.predict() should also accept a single float value instead of forcing me to write it as an array containing a single element. or exampl
For example-
from impedance.models.circuits import CustomCircuit
RC_parallel=CustomCircuit("p(R0,C0)",initial_guess=[1e2,1e-3])

print(RC_parallel.predict([9]))
and
print(RC_parallel.predict(9))

should both be valid.

But as of now, the print(RC_parallel.predict(9)) gives error.
