Files-to-prompt

- Warn and skip non-UTF-8 files, rather than crashing. Warnings are printed to standard error. [5](https://github.com/simonw/files-to-prompt/issues/5)

- New `--ignore '*.md'` multi-option for providing additional patterns to ignore. Thanks, [Dipam Vasani](https://github.com/dipam7). [#1](https://github.com/simonw/files-to-prompt/issues/1)
- `files-to-prompt` can now be passed multiple files and directories as arguments, for example `files-to-prompt my_app.py tests/`. [2](https://github.com/simonw/files-to-prompt/issues/2)

- Initial release. Run `files-to-prompt .` to concatenate together the current directory contents into a prompt suitable for piping to an LLM.
