Returns true if x is a narcissistic number.

aind_warmup_is_narcissistic.py

"""A _narcissistic number_ is an `n`-digit whole number that is equal to the 
sum of its digits raised to the power `n`.
For instance, `153` is such a 3-digit number (`1^3 + 5^3 + 3^3 = 153`)
and `8208` is a 4-digit example (`8^4+ 2^4 + 0^4 + 8^4 = 8208`).

Write a function `is_narcissistic(x)` that returns _true_ if `x` is
narcissistic. Now use this to find as many narcissistic numbers as you can.
How high up can you go?

Note: 1-digit numbers are all trivially narcissistic, so you may skip them.
