@iarna/toml

With 2.0.0, @iarna/toml supports the TOML v0.5.0 specification. TOML 0.5.0
brings some changes:

• Delete characters (U+007F) are not allowed in plain strings. You can include them with
  escaped unicode characters, eg \u007f.

• Integers are specified as being 64bit unsigned values. These are
  supported using BigInts if you are using Node 10 or later.

• Keys may be literal strings, that is, you can use single quoted strings to
  quote key names, so the following is now valid:
  'a"b"c' = 123

• The floating point values nan, inf and -inf are supported. The stringifier will no
  longer strip NaN, Infinity and -Infinity, instead serializing them as these new values..

• Datetimes can separate the date and time with a space instead of a T, so
  2017-12-01T00:00:00Z can be written as 2017-12-01 00:00:00Z.

• Datetimes can be floating, that is, they can be represented without a timezone.
  These are represented in javascript as Date objects whose isFloating property is true and
  whose toISOString method will return a representation without a timezone.

• Dates without times are now supported. Dates do not have timezones. Dates
  are represented in javascript as a Date object whose isDate property is true and
  whose toISOString method returns just the date.

• Times without dates are now supported. Times do not have timezones. Times
  are represented in javascript as a Date object whose isTime property is true and
  whose toISOString method returns just the time.

• Keys can now include dots to directly address deeper structures, so a.b = 23 is
  the equivalent of a = {b = 23} or [a] b = 23. These can be used both as keys to regular tables and inline tables.

• Integers can now be specified in binary, octal and hexadecimal by prefixing the
  number with 0b, 0o and 0x respectively. It is now illegal to left
  pad a decimal value with zeros.

Some parser details were also fixed:

• Negative zero (-0.0) and positive zero (0.0) are distinct floating point values.

• Negative integer zero (-0) is not distinguished from positive zero (0).
