0a79d6c1f7 Fix out-of-bounds read in lexer comment/hashbang skipping 
skipSingleLine, skipSingleLineComment, and skipMultiLineComment incremented
the source index and then called peekCharWithoutEOF() without re-checking
eof(), causing a one-byte heap read past the source buffer when the input
ends with a bare \r or a trailing '*'. Guard each follow-up peek with eof().

Fixes #1568

97e8115ab1 Add basics of Chrome Devtools debugger support 
- Use routing table for request dispatch in DebuggerHttpRouter, for
  handling choosing which debugger stack to use based on the http
  upgrade request:
    - DebuggerEscargot for the python debugger and VSCode
    - DebuggerDevtools for connecting to Chrome Devtools
- Parse mesasges with 16bit message size
- Reply to the first few messages chrome sends
- Refactor Debugger:
    - Rename DebuggerRemote to DebuggerEscargot
    - DebuggerEscargot and DebuggerDevtools inherit from
      DebuggerTcp which inherits from Debugger
- Add debugger info to README.md
