Improvements and questions from SwaySwap development

Improvements and questions

• Transaction error returns are not detailed enough; We need to debug binaries, etc.
• Transfer coins need to have a script id. It's possible to use a script already implemented on the Core; we
  have used the id 0x24400000 , but it would be nice to have some table with available scripts and what they do.
• scriptData needs to have random data every time to make transactions different. known issue.
• It's challenging to work with amounts; we should have something like https://docs.ethers.io/v5/api/utils/display-logic/#utils-parseUnits
• Empty values were not parsed, resulting in type is not found on the ts SDK. fix!: Handle empty value in abi #134 should fix it.
• Generate Contract factory with fuels dependency #183
  • The readme is not clear it should install the dependencies;
  • I had the dependency fuels on the project and had to install the specific dependencies or change manually on the generated file. Maybe we should check if the fuels is installed and use it or If it is not possible to check. We could use fuels as a preferable dependency.
• We don't have a tutorial explaining how to do a full demo; we could use swayswap to create something like this.

I just implemented it here: FuelLabs/fuels-rs#110. Maybe that could help you with this point!
