Conditional Imports for Raspberry Pi

[mattdonders]

Due to installation time and resources for Pandas & Numpy, create conditional imports so that section of code just skipped.

When shotmap functionality is introduced break up the requirements file into these two options -

• Base requirements & shotmap / data science extras : requirements.txt and requirements-extras.txt
• Two separate files per platforms : requirements-rpi.txt and requirements-all.txt

Started by removing unused imports and cleaning up as mentioned in the above commit. Will move to conditional imports and requirements file when the shotmaps stuff is implemented directly into the bot.
