fortuna: handle reseeds+clear pools for seed 
* actually clear out entropy of the pools before a reseed
* correctly prepare the seed for the reseed
* add a couple of helper methods to Pool that assist with getting
  length, retrieving and clearing of the collected entropy
* catch exceptions in main(), handle them gracefully

finalise generator 
commit a64b52e5a4
Author: surtur <a_mirre@utb.cz>
Date:   Sun Nov 21 23:39:30 2021 +0100

    finalise generator

    this commit adds a (nearly) complete implementation of the generator.

    * wrap calls to generator in a fortuna class method random_data
      * calls generator's method generate_random_data, that internally calls
        generate_blocks
    * use a proper 256bit key in G_state
    * add reseed method implementation
    * call a reseed in initialize_generator
    * do_sha returns proper digest now
    * add proper do_crypto implementation
      * call generate_blocks internally
      * handle re-keying
    * optimise header includes

    TODO: there are still many commented (enabled on demand) debugging statements
    -> TO BE REMOVED

feat: use fmt instead of iostreams 
switch to fmt - "A modern formatting library" - for fun and profit,
currently in header-only configuration.

Date:   Wed Nov 3 02:14:35 2021 +0100

    chore: make G_state a private structure

    * make G_state private
    * move protected section behind private
    * also do cleanup a little -> k and ctr won't exist as part of the
      generator outside of the G_state struct

    chore: make methods aware of objects

    as a consequence we stopped returning the generator state from every
    function and equally stopped using it as a parameter to every generator
    method that handles the state in any way

Author: surtur <a_mirre@utb.cz>
Date:   Tue Nov 2 05:10:58 2021 +0100

    feat: move from structural to object paradigm

    * declare and implement Generator class and member methods
    * create an instance of Generator in main
    * call initialize_generator() from main
