Refactor of aal.c

[MkeyBeez]

Implements addition, subtraction, multipilcation, division, and modulo operations.

We cast everything to a struct BigFloat to unify common operations needed for string arithmetic.
Multiplication for numbers longer than 32 digits uses recursive karatsuba, one can of couse tune the amount of digits to specify exactly when this kicks in; I have not done extensive benchmarks yet.

The easiest way to try out the proposed implementation is to open the attached colab.ipynb in a google colab instance and execute the notebook. You can then try the operations interactively.

Implementation of Square roots should be easy with an iterative algorithm, Implementing string exponentiation is a bit more tricky since this requires logarithm operations in non integer cases. Let me know what you think.
