[Feature] ENS normalise

### Component

other

### Describe the feature you would like

ENS crate doesn't have ```normalise``` function. This is needed as it was stated in [ENSIP-15](https://docs.ens.domains/ensip/15/). Normalise parses the domain before passing it to the resolver smart contract.

There are 2 ways i can go about this:
1. Use [ens-normalize-rs](https://crates.io/crates/ens-normalize-rs), to implement the function. This helps by reducing code needed to maintain.
2. Creating from scratch the normalization algorithm. Ideally i would not recommend this, but I can work on it.
