[🚀 Feature]: Replace https://github.com/asafh/jtoml as it has been abandoned

### Feature and motivation

This TOML parser is used to read the configuration file in Grid, the code has been abandoned and it might have vulnerabilities. 

### Usage example

We could replace it with https://github.com/tomlj/tomlj, and it is the only one with recent releases.

Worst case, fork the one we use and update it.
