This library does not appear to pass all tests in toml-test

I took a look at this library today, and it appears that it is not actually a correct implementation of TOML 1.0.0. I tried running some of the tests in https://github.com/BurntSushi/toml-test , using a janky racket back-end to spit out JSON encodings. While this back-end is very incomplete, the resulting test failures suggest that your TOML library is not correctly parsing a bunch of the different TOML 1.0.0 string forms. Here's one example input from the test library:

      backspace = 'This string has a \b backspace character.'
       tab = 'This string has a \t tab character.'
       newline = 'This string has a \n new line character.'
       formfeed = 'This string has a \f form feed character.'
       carriage = 'This string has a \r carriage return character.'
       slash = 'This string has a \/ slash character.'
       backslash = 'This string has a \\ backslash character.'

It produces this output:

(root ("backspace" . "Parser Error: invalid literal or str")
  ("tab" . "Parser Error: invalid literal or str")
  ("newline" . "Parser Error: invalid literal or str")
  ("formfeed" . "Parser Error: invalid literal or str")
  ("carriage" . "Parser Error: invalid literal or str")
  ("slash" . "Parser Error: invalid literal or str")
  ("backslash" . "Parser Error: invalid literal or str"))

Here's another one:

      # Single ' should be allowed.
       oneline = '''This string has a ' quote character.'''
       
       # A newline immediately following the opening delimiter will be trimmed.
       firstnl = '''
       This string has a ' quote character.'''
       
       # All other whitespace and newline characters remain intact.
       multiline = '''
       This string
       has ' a quote character
       and more than
       one newline
       in it.'''

it produces this error:

(root
  ("oneline" . "Parser Error: invalid literal or str")
  ("firstnl" . "Parser Error: invalid literal or str")
  ("multiline" . "Parser Error: invalid literal or str"))
