Fix netProbe write check
...
Write at least 1 byte. This ensures that sockets are ready to use for writing.
Windows specific: during the system startup, sockets can be created but the underlying buffers may not be setup yet. If this is the case Write fails with WSAENOBUFS: "An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

2d1dd7eaab
Add Stretch-Hash-and-Truncate option for extreme DNS privacy
...
This works over DNSCrypt and DoH, but requires a specifically configured
server.
Instead of sending the actual DNS queries, the SH-T system works as follows:
Step 1: the client query is evaluated through Argon2id, a military-grade,
memory-hard, CPU-hard stretching function. This makes it very expensive
for an attacker to find the original query, even using GPUs and ASICs.
For post-quantum resistance, we use it to generate a 1024-bit key.
Step 2: in case the Argon2id algorithm has a vulnerability, or, since this
is a popular function used for hashing passwords and for cryptocurrencices,
and people may have built rainbow tables already, we use a hash function over
the result of the previous function. This immediately defeats rainbow tables.
Step 3: the output of the hash function is truncated to 64-bit.
Due to a property of this operation known as collision-misresistance, and even
if the previous steps fail due to a nation-state actor, it is impossible for a
server operator to prove what exact query was originally sent by a client.
This feature is experimental.

Fixing #304 doesn't look trivial
The service module needs to know the arguments right away.
The arguments haven't been parsed yet. And if we do, we will prevent
further arguments to be added to the set. Including the ones added
by the service module itself.
So, we have quite of a circular dependency here.
If someone with some Go knowledge can fix that, that would be amazing.
But it's probably never going to happen.
Meanwhile, we can try to save the current directory and document
that we have to be in that directory when running the install command.
Which is not going to work on Windows, so this is a big fucking mess
