Update sqlparse to 0.4.1

[pyup-bot]

This PR updates sqlparse from 0.3.1 to 0.4.1.

Changelog

0.4.1

----------------------------

Bug Fixes

* Just removed a debug print statement, sorry...

0.4.0

----------------------------

Notable Changes

* Remove support for end-of-life Python 2.7 and 3.4. Python 3.5+ is now
required.
* Remaining strings that only consist of whitespaces are not treated as
statements anymore. Code that ignored the last element from
sqlparse.split() should be updated accordingly since that function
now doesn't return an empty string as the last element in some
cases (issue496).

Enhancements

* Add WINDOW keyword (pr579 by ali-tny).
* Add RLIKE keyword (pr582 by wjones1).

Bug Fixes

* Improved parsing of IN(...) statements (issue566, pr567 by hurcy).
* Preserve line breaks when removing comments (issue484).
* Fix parsing error when using square bracket notation (issue583).
* Fix splitting when using DECLARE ... HANDLER (issue581).
* Fix splitting of statements using CASE ... WHEN (issue580).
* Improve formatting of type casts in parentheses.
* Stabilize formatting of invalid SQL statements.
