feat: very experimental support for scanning on a remote host

[AlCalzone]

With this PR, we can have the scan process run on a remote host and send its received data via TCP.
This is very experimental and guaranteed to be unstable.

Installation of the ble server is currently manual:

# create and enter a directory where it should be installed
# ...

# Install the desired version of noble
npm i @abandonware/noble@1.9.2-21

# Copy bin/blerp.js from this repository into the folder

# run it
sudo node blerp.js -s <services>

To use this, set the server address in the configuration to <hostname or ip>:<port> and start the adapter.
