Description

**Describe the bug**
According to ASCII85 from Adobe ([https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf](https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf) page 33) if you find 4 null chars, it should output a "z" and if you are decoding and find a "z" you should output five null chars

**To Reproduce**
Try to decode "z" in Base85

https://gchq.github.io/CyberChef/#recipe=From_Hex('Auto')To_Base85('!-u',false)&input=MDAgMDAgMDAgMDA

Should output 'z'for Base85/ASCII85 Adobe version
