Merge bitcoin/bitcoin#27516: test: simplify uint256 (de)serialization routines
96bf0bca4a0e3aa0b7c07d8c225861e72f970fa9 test: simplify uint256 (de)serialization routines (Sebastian Falbesoner) Pull request description: These routines look fancy, but do nothing more than converting between byte objects of length 32 to/from integers in little endian byte order and can be replaced by simple one-liners, using the `int.{from,to}_bytes` methods (available since Python 3.2).
