(https://github.com/ruby/yarp/pull/1371)
* refactor: move EOF check into yp_unescape_calculate_difference
parser_lex is a bit more readable when we can rely on that behavior
* fix: octal and hex digits at the end of a file
Previously this resulted in invalid memory access.
* fix: unicode strings at the end of a file
Previously this resulted in invalid memory access.
* Unterminated curly-bracket unicode is a syntax error
