ActiveFocuser has a dependency on libhdiapi-hidraw0

[AnakChan]

The new Takahashi ActiveFocuser on the latest Astroberry build has a few issues :-

1. dependency on libhidapi-hidraw0 - need to apt install libhidapi-hidraw0

2. Upon installation the /dev/hidraw0 has the wrong permissions which can't be read needing a new udev rule :- crw------- 1 root root 244, 0 Mar 10 09:48 hidraw0 astroberry@astroberry:/etc/udev/rules.d $ cat 51-activefocuser.rules KERNEL=="hidraw*", ATTRS{idVendor}=="20e1", ATTRS{idProduct}=="0002", MODE="0666", GROUP="plugdev" SUBSYSTEM=="usb", ATTR{idVendor}=="20e1", ATTR{idProduct}=="0002", MODE="0666", GROUP="plugdev"
