Description

Hi, I just installed your tool and tried doing hson <file.json>, where the file also contains comments (jsonc file basically), and I get an error:

Error: failed to parse input file: ./nvim/misc-files/vimspector/go.json

Caused by:
    InternalError(TapeError) at character 0 ('/')

Contributor guide

Research direction
Research how to parse JSON with comments (JSONC) in Rust, possibly using the 'serde json' crate with a custom deserializer or a library like 'jsonc parser'. Implement a preprocessing step to strip comments before parsing.
