The Encoding.DecodedLen API only returns the maximum length of the expected decoded output, since it does not know about padding. Since we have the input, we can do better by computing the input length without padding, and then perform the DecodedLen calculation as if there were no padding. This avoids over-growing the destination slice if possible. Over-growth is still possible since the input may contain ignore characters like newlines and carriage returns, but those a rarely encountered in practice.
