New features:

• Support upcoming TOML 1.1

  While it looks like TOML 1.1 is mostly stable and I don't expect any further major changes, there are NO compatibility guarantees as it is NOT yet released and anything can still change.

  To use it, set the BURNTSUSHI_TOML_110 environment variable to any value, which can be done either with os.SetEnv() or by the user running a program.

  A full list is changes is available in the TOML ChangeLog; the two most notable ones are that newlines and trailing commas are now allowed in inline tables, and Unicode in bare keys can now be used – this is now a valid document:

  lëttërs = {
    ä = "a with diaeresis",
    è = "e with accent grave",
  }

• Allow MarshalTOML and MarshalText to be used on the document type itself, instead of only fields (#383).

Bufixes:

• \ escapes at the end of line weren't processed correctly in multiline strings (#372).

• Read over UTF-8 BOM (#381).

• omitempty struct tag did not work for pointer values (#371).

• Fix encoding anonymous structs on 32bit systems (#374).
