Possibility to convert exported TSM backup files to other formats like CSV or JSON

A newbee question:
I've searched in the issues and in the internet but couldn't find any hint. I've checked all InfluxDB CLI tools and available commands of them.

I've a use-case that I need to do analysis on backup TSM data, however, I couldn't find how to read them programatically. The best would be to read data using Python pandas library.

If it is not possible, I can develop a tool in GoLang to convert `.tsm` file to some CSV/JSON format. I'm looking for the general possibilities and some directions.

How I took backup: `influxd backup -portable influx_backup`
InfluxDB version: `1.7.8`

Start with the `influxd backup -portable influx_backup` entry point and the stated InfluxDB 1.7.8 context. Compare the requested Python/pandas approach with the proposed Go conversion tool, but clarify the intended input, output formats, and acceptance criteria before implementation; the issue currently does not define what done looks like.
