[pyup-bot]

This PR updates sqlparse from 0.4.3 to 0.4.4.

Changelog

0.4.4

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

Notable Changes

* IMPORTANT: This release fixes a security vulnerability in the
parser where a regular expression vulnerable to ReDOS (Regular
Expression Denial of Service) was used. See the security advisory
for details: https://github.com/andialbrecht/sqlparse/security/advisories/GHSA-rrm6-wvj7-cwh2
The vulnerability was discovered by erik-krogh from GitHub
Security Lab (GHSL). Thanks for reporting!

Bug Fixes

* Revert a change from 0.4.0 that changed IN to be a comparison (issue694).
The primary expectation is that IN is treated as a keyword and not as a
comparison operator. That also follows the definition of reserved keywords
for the major SQL syntax definitions.
* Fix regular expressions for string parsing.

Other

* sqlparse now uses pyproject.toml instead of setup.cfg (issue685).
