TYPO3 Core

As we log some custom events to `sys_log` we installed the log extension https://gitlab.com/co-stack.com/co-stack.com/typo3-extensions/logs mentioned at https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/Logging/Writers/Index.html.

The backend module sorts the log entries by the field `time_micro` of the table `sys_log`. However, the entries in this field getting stored not correctly because the type is defined as `float`
(https://github.com/TYPO3/TYPO3.CMS/blob/650d5d7ba771d2ad854f2475b7b7d4aff70c9d2c/typo3/sysext/core/ext_tables.sql#L384). While the real microtime in PHP was something like `1617029996.5212` I got `1617030000` in all records:

Changing the type to `decimal(14,4)` fixed the issue.
