toml fixer

**Name:** toml
**URL:** https://github.com/segeljakt/toml-fmt

toml is widely used these days(rust, poetry, ansible,etc)

I could not find a linter for it however I do find the above toml-fmt works on the command line, but I could not add it to ALE somehow. below is what I tried(after install `cargo install toml-fmt`):

```
