ATOMIO - Crate to parse molecular formula

Parse chemical formula like CH4, Al2(SO4)3, K2Cr2O7 etc.

Usage is simple:

```rs use atomio::{parser::Parsed,element_group::Unit};

let parsed = Parsed::fromstr("CH4"); assert!(parsed.rootgroup, Unit::ElementGroup {count:1, units: vec![ Unit::Element { count: 1, symbol: "C".into() }, Unit::Element { count: 4, symbol: "H".into() } ]}) ```
