- There are problems when running the server in a separate thread on arduino nano 33 ble, while it works on qemu_x86:
```
<err> os:   Stacking error (context area might be not valid)
<err> os:   Data Access Violation
```
Therefore for now we are running the server thread in the main thread in blocking mode.

- CoapSite::set_sock is now static and move set_sock call from start_server into CoapServer constructor
- Add check if no resource directory is found in the network then stop execution of the program.

link-local addresses require interface name to be specified.
For example a correct url with link-local ip would be the following: `coap://[fe80::c63:43ed:a8ef:2ab3%wlx1cbfcedf85d7]:5683`
We are using getnameinfo to get the correct interface name from the address. 
As a consequence, url query must be percent-encoded so that the base address is correctly decoded
