KVMD 1.71: Improved IPMI server

The new version comes with two improvements.

First off, we improved the IPMI server. The ipmiutil health command is now supported.

Secondly, in the web interface, you can now record a macro of your keyboard and mouse actions on the server, save it, and play it back.

This is convenient if you need to perform a sequence of similar actions. The downloaded macro has a convenient json format, so you can independently write scripts with macros in any convenient language to play them remotely.

For example, this is a Python script that plays a macro on the specified PiKVM.
