fix(parser): Parse event name when using an identifier (#1)

[soft-decay]

• Add utils functions to help parse identifiers:
  • isPunctuatorToken (used internally in utils)
  • buildObjectFromObjectExpression (used internally in utils)
  • buildPropertyAccessorChainFromTokens (v2 parser only)
  • buildPropertyAccessorChainFromAst (v3 parser only)
  • getValueForPropertyAccessorChain (_v2 and v3 parsers)
• Fix potential bugs:
  • utils.value was mutating the argument
  • parseEventDeclaration could attempt to read property of 'undefined'
• Add/Update tests (3) for event name parsing in parser v2 and v3
• Add unit tests (9) for new utils function

TODO:

• [x] Add missing tests for utils functions edge cases
• [x] Add missing tests for event name parsing in other contexts
• [x] Finish documentation
• [x] Cleanup code

Please let me know when you are ready with this PR, for me the current status is OK

[soft-decay]

I've completed the missing tasks. It should be good to merge. There were some minor code change so you should check if everything is ok with you.
