This PR identifies all those instances and replaces them with a newly introduced helper `tx_from_hex`. Instances were found via * `git grep "deserialize.*BytesIO"` and some of them manually, when it were not one-liners. Further, the helper `ToHex` was removed and simply replaced by `.serialize().hex()`, since now both variants are in use (sometimes even within the same test) and using the helper doesn't really have an advantage in readability.
