[riot-notifications] [RIOT-OS/RIOT] pkg/openwsn: re-integrate the network stack as a package (#13824)

I got a basic setup (disabled channel hopping) running now as described in the README of the test application. It transmits UDP packets between two nodes  in both directions over the root node. IEEE802154E synchronization and the RPL topology seems stable.

Sometimes I got this (on a leaf node) after flashing, and the node needed a reset:

```
ifconfig
inet6 ::
hwaddr short: 00:00    long: 00:00:00:00:00:00:00:00
panid: 00:00

IEEE802154E sync: 0

6tsch joined: 0

NO RPL parent
```

Then (with default channel hopping enabled but I don't know if it relates) it appeared that many packets got lost (not received by UDP server), though, I cannot really reproduce this. Eventually, this relates to one of the error logs printed on the root node:

```
[ParserIEC:ERROR] 5486 [IEEE802154E] wdDataDuration overflows while at state 19 in slotOffset 0
```

```
[ParserIEC:ERROR] 5486 [OPENSERIAL] wrong CRC in input Buffer
```
