TODO: new release

[shwestrick]

We've had a few nice changes since v1.0.0!

• safety checks #77: --safety-check flag for checking that the output of smlfmt is correct, i.e., that the result is valid SML that exactly matches the source except for whitespace.
  • Note: originally called --check but renamed to --safety-check in Add flag to check if files are formatted #92.
• feat: Make --stdio the default for non-tty stdin #84, Remove --stdio flag #86: automatically detect when stdin / stdout should be used.
• feat(cli): add read-only flag #87: --read-only flag, useful for checking for syntax errors
• Add "make install" target. #93: make install formula
• Add flag to check if files are formatted #92: --check flag, to check if a file has already been formatted. Useful for CI.
• Some bugfixes, e.g. 656885b

It would be nice to get #92 in before this next release, since that is in the works. Done.

Also, we should add mention of https://github.com/diku-dk/smlfmt.el to the README, perhaps in feature list. Done.
