Taupe

This release only corrects inconsistent statements about the license terms of the software. There are no functional or other changes in this release.

This update brings more output format options. The option `--extract` now accepts many more values to control the output. For example, It is now possible to produce a plain list of URLs of your tweets. Please see the help text or the [README](https://github.com/mhucka/taupe#the-structure-of-the-output) for the details.

Changes since the last release:
* The [README](https://github.com/mhucka/taupe/blob/main/README.md) has been edited and enhanced.
* The help text printed for `taupe --help` has been edited to (hopefully) improve clarity.

First release of complete working version.
