Concurrency is a good way to trigger any interleaving bug.

They can be enabled with `GGTX_LOG_LEVEL` during tests.

The bug is elsewhere.

This commit extends the timeout around the `readTChan` in the ping-pong
test to 60 seconds, mostly to account for CI slowness and to rule-out
potential source of flakyness.

The calls to `threadDelay` have been removed, as they doesn't seem to
affect the overall stability of the test (at least locally) -- the
point of the exercise is trying to expose as much as possible potential
problems which might be masked by active waits.

Before we were repeating the same code to initialise all the different
loggers. This commit introduces two stock loggers called `ioStdLogger`
and `monadicStdLogger` which can be reused many times.

It also allows the `GGTX_LOG_LEVEL` to take effect during `readConfig`,
so that the `startupInfo` would show up the correct information.

This commit fixes a bug where a user member of a team (but NOT the owner
of such team) couldn't move nodes.

The problem was caused by the improper usage of
`delegate_ctrl` when creating the coreNLP process. For a long
time I was under the impression this flag was essential to allow child
processes to shutdown cleanly without leaving zombie threads, but the
result here in the context of the testsuite was that the coreNLP server
was receiving the first Ctrl^C, completely starving the Haskell RTS,
which wouldn't receive any and as a result our testsuite would be
running forever.

This commit correctly propagates the correct `LogConfig` in all the
places where we were just defaulting to log everything, and this allows
us to silence debug logs in tests, unless we want them.

This will allow us to find all the use site of this function, trying to
see if we can use only `withLogger` or correctly control the logging
verbosity via the `HasLogger` and `LogInitParams`.

We are now around 6/7 times slower than the LLVM code.

This also changes the cabal.project to not pull the accelerate-llvm or
the llvm-hs dependencies.

There are some rounding errors in the tests, but otherwise
the implementation seems correct.

This commit starts introducing `massiv` in the codebase,
initially for simple functions like `termDivNan`. The main
goal is to extend the linear algebra toolkit up to the
point where we can implement `distributional` in terms of
`massive` and measure its performance.

The previous code was sometimes yielding a matrix of NaN numbers as
it was attempting the division of the input matrix with the diagonal,
which would be 0 in case of an input matrix of 0, resulting in a
division by 0 error.

The main idea is trying to refactor/improve the existing linear algebra
functions one function at the time, using reference implementations and
benchmarks along the way.
