- Update specfile for PEP517 and python packaging best practices

- update to 1.1.0:
* Fixed an issue in the Nickname profile implementation that
trimmed extra leading/trailing white space beyond the `Zs`
category prescribed in RFC 8266. Python treats certain
Unicode control characters as white space. If these appeared
as leading/trailing spaces in a Nickname string, they
were stripped. With this release, the Nickname profile will
raise a UnicodeEncodeError `DISALLOWED/controls` if any control
characters are encountered. (Issue #29)
* Update internal tables for Unicode 15.1.
* Change format of README and CHANGELOG files to Markdown.
* Drop support for Python 3.3 and 3.4.

* get_profile now supports alternative unicodedata2 module
* get_profile maps ':' to '_' before looking up profile name
- Drop support_unicode_12.1_for_python_3.8.patch
