* Use `let()` syntax for bindings
This lets users use destructuring when binding more complex values, and we also get better IDE support.
* Update rstml
* Feat: Upgrade to new local version of syn-rsx
* chore: Make macro more IDE friendly
1. Add quotation to RawText node.
2. Replace vec! macro with [].to_vec().
Cons:
1. Temporary remove allow(unused_braces) from expressions, to allow completion after dot in rust-analyzer.
* chore: Change dependency from syn-rsx to rstml
* chore: Fix value_to_string usage, pr comments, and fmt.
