   Only one function is imported in script.py. Just move that function to script.py and remove the bignum.py module.

   Remove unused functionality and fix some flake8 warnings along the way.

2. [tests] fix flake8 warnings in script.py and bignum.py f31fc0e92e
3. [tests] add function comments to bignum 1dc68aee66
4. [tests] don't encode the integer size in bignum

   We just throw it away whenever we use the
   result so don't add it.

5. [tests] remove mpi2vch() function

   All it does is reverse the bytes order.

6. [tests] remove bn_bytes() function

   It is one line and is called in one place.

7. [tests] remove bn2bin()

   It's only called in one place.

   I’m confused by the commit order here. First you add comments to bignum, then you remove the whole module.

    This import should go, I guess?

    Comments are for the benefit of reviewers so they can see what functionality is being moved around.

12. [tests] remove bignum.py

    It only contains one function and is only imported by one
    other module (script.py). Just move the function to
    script.py.

    I’d be ok with keeping the bignum module, just removing the functions that are no longer used. Not sure script.py is a much better place for that function.

    Concept ACK on removing functions that are no longer used or tested
