This adds an overflow check in `Script::bytes_to_asm_fmt()` motivated by `electrs` issue. While it was not tested yet, I'm very confident that overflow is the cause of panic there and even if not it can cause panic becuase the public function takes unvalidated byte array and reads `data_len` from it. The `electrs` issue: romanz/electrs#490
This adds a test case for script formatting which caused overflow in the past and a few others from the same "interesting" transaction. Note that to trigger the bug one has to run the test on 32 bit architecture.
