[Add Sui Support]

It is being added here as a draft in case the team wants to provide context or comments. Some unit testing is done but it is awaiting local development testing using Sui wallets and guidance around the addition of CAIP's for Sui network(see below)

Hi, is there any progress with Sui support? I'm considering using composedb with Sui chain. I may not be familiar with signing algorithms, but is there any further information I can learn or help with?
