Support svelte parser

[sxxov]

Is there a list of things that need to be implemented before svelte can be supported? Would love to help/contribute.

I don't have a list, but I would like to complete the following tasks before supporting the new parser:

• Reinforce testing of existing parsers and determine formatting policies (currently in progress)
• Refactoring of core parts
  • Modify the ClassNameType enum to be a combination of multiple properties (It feels similar to combining Tailwind CSS utility classes.)
  • Improve the process of finding class names in AST and wrapping them (I'm considering something like introducing an abstract class, but haven't thought about it in more detail.)

Recent updates:

• As part of the core parts refactoring plan, modifications to the ClassNameType enum are complete.
• I decided to postpone improving the process of finding class names in AST and wrapping them around lines because no specific plan has been decided.
• Reinforce testing of existing parsers and determining formatting policies are almost complete.
