clp-s: Incorrect parsing of string values when followed by a number of spaces.

[wraymo]

Bug

Currently, clp-s uses raw_json_token().substr(1, raw_json_token().size()-2) to get unescaped string values. But according to the official docs, a string token always begins with a " and is always terminated by the final ", possibly followed by a number of spaces. A string may not be correctly parsed if it is followed by spaces.

CLP version

Environment

macOS 13.2.1

Reproduction steps

• Compress a file with a log message {"a": "clp string" }
• Decompress the archive. The log message becomes {"a": "clp string""}
