```

adds a new route /device/send-wol/:mac-addr to send the magic WOL package
to the specified mac-addr.
Method is POST and is protected.

Useful for custom wake up scripts: example is sending HTTP request through iOS shortcut

Test plan:
calling the API with curl
```
$ curl -X POST   http://<jetkvm-ip>/device/send-wol/xx:xx:xx:xx:xx:xx
WOL sent to xx:xx:xx:xx:xx:xx
```

and observing the magic packet on my laptop/PC:
```
$ ncat -u -l 9 -k | xxd
00000000: ffff ffff ffff d050 9978 a620 d050 9978  .......P.x. .P.x
00000010: a620 d050 9978 a620 d050 9978 a620 d050  . .P.x. .P.x. .P
00000020: 9978 a620 d050 9978 a620 d050 9978 a620  .x. .P.x. .P.x.
00000030: d050 9978 a620 d050 9978 a620 d050 9978  .P.x. .P.x. .P.x
00000040: a620 d050 9978 a620 d050 9978 a620 d050  . .P.x. .P.x. .P
00000050: 9978 a620 d050 9978 a620 d050 9978 a620  .x. .P.x. .P.x.
```

calling the api with invalid mac addr returns HTTP 400 error
```
$ curl -X POST -v http://<jetkvm-ip>/device/send-wol/abcd
...
* Request completely sent off
< HTTP/1.1 400 Bad Request
...
...
Invalid mac address provided
