-----------
refactor: remove boost dependency
implement our own Runge-Kutta54 Cash-Karp, that boost::ode
uses in integrate() as claimed in documentation:
https://www.boost.org/doc/libs/1_66_0/libs/numeric/odeint/doc/html/boost_numeric_odeint/getting_started/short_example.html
Algorithm described here
http://www.elegio.it/mc2/rk/doc/p201-cash-karp.pdf
As far as I tested, it gives the same results.

Log Message:
-----------
refactor: use runge kutta method as described in original paper
it seems the previous implementation sometimes enter in an infinite loop
In my tests, however, some parts of this new code are never reached.
That's the reason the code could be simplified to only this `if` branch
```c++
if (e_4 > 1) {
// No order less than 5th order is possibly good, so
abandon current step
Real esttol = e_4;
step_size *= std::max(0.2, VRKF_sf / esttol);
continue;
} else {
// accept 5th order solution
...
}
```
And consequently some variables could vanish.
