when I use CyberChef to implement the cfb encryption of aes, the corresponding encryption mode is not found in chepy.

An example of CyberChef is shown in the figure：

But there is no cfb mode for aes in chepy:

Thank you for opening the issue @shengchenyang . I have implemented CFB mode for AES. Do keep in mind that pythons default behavior uses CFB8 mode while CyberChef uses CFB128. Chepy implements CFB128 to stay inline with CyberChef.
