Julian Oes e101edc0e7 Matrix: fix warning if M == N (#146) 
This fixes the warning appearing with GCC 10.2:

../../src/lib/matrix/matrix/Matrix.hpp:481:34: error: logical ‘and’ of equal expressions [-Werror=logical-op]
  481 |         for (size_t i = 0; i < M && i < N; i++) {
      |

I would prefered something with if constexpr but we don't have that yet
in because we're using C++14.

Matthias Grob 7a3009f7a3 Remove asserts for unsigned integer >= 0 
GCC 10 gives a warning
"comparison of unsigned expression in ‘>= 0’ is always true"
for these asserts since checking if an unsigned integer cannot
be negative and hence the statement gets droped.

Matthias Grob a32892926c Matrix: capture stdout for print() test 
I want to switch the print() function back to use printf()
such that it's fully compatible with all (embedded) platforms.

To still test the print function I'm capturing stdout into a file
such that the print() function can stay unchanged and the result of
the printf()s can be evaluated.

Matthias Grob c6db357c92 Matrix: correct print buffer size prediction 
Apparently printf of %8.8g can result in
8 significant digits + dot + scientific notation e.g. "e+12" = 14 bytes

Matthias Grob 33a629105c Matrix: add proper print function testing 
Before the print function was just implicitly called somewhere
and that's why we had 100% line coverage. With this we have actual
testing of the functions.

Matthias Grob 9c0acfba36 Matrix: remove unsafe copyToRaw method 
It used a pointer and could therefore not do correct type checking
for index out of bound or struct memebr order.
Has to be considered unsafe and bad practise.
We should switch to arrays as representation for vectors
inside the messages instead of foo_x, foo_y, foo_z fields.
