create 64 bit version

[JanLahmann]

Qiskit can also be installed on the 64 bit version of Raspberry Pi OS, https://downloads.raspberrypi.org/raspios_arm64/images/
Need to check if all other components work as well on 64 bit OS.
Then decide whether to make 64 bit the default for RasQberry.

pip3 install --upgrade pip
sudo apt -y install libhdf5-dev llvm-9
LLVM_CONFIG=llvm-config-9 pip3 install llvmlite
pip3 install --prefer-binary qiskit[all]==0.26.*
pip3 list | grep qiskit

This change will also allow for further optimizations in Python Scripts (e.g. the Fractal Demo) as data-heavy computations can be converted to using Numba over Numpy as Numba is more or less only compatible with a 64-bit OS.
