The bitcoinsuite dependency implements Display trait for scripts now.
Opcodes are displayed by their respective names.
PUSHDATA payloads are displayed either in hex with 0x prefix or as a quoted string given it's a valid UTF-8 string containing only alphanumeric characters in any language, whitespace, diacritics, symbols or emojis.
A 0x00 byte at the end of string is displayed as \0 (this is a special case for SLP tokens to look nice).

Run unit tests in bitcoinsuite-core project.
Run explorer-exe, navigate to some transaction, switch to Advanced mode and see if Script Decoded fields show human-readable scripts.
