[CHORE] Break Repo into parts

[GalloDaSballo]

Because Brownie allows to import Github Repos we should just chunk the code into parts and import it back, this will avoid having thousands of tests and will keep the code simpler overall

• CowswapSeller -> Functions for Cowswap
• Processors -> BribesProcessors
• OnChainPricer and Executor -> Prices stuff and runs swaps
• Cowswap Limit Order Protocol -> TODO, but should be separate
