Centralized ccxt requirement.

What's the rationale for porting ccxt "back" into the main requirements.txt? It shouldn't be needed at that level for the project to work properly, isn't it?
I feel it already is a dependency of something else, but it might be just my custom environment I'm getting confused about.

If ccxt shouldn't be in the base requirements, what's stochastic doing there? Since they're both included in the code, (ccxt in tensortrade/data/cdd.py and stochastic in tensortrade/stochastic/), I thought they could be in the base requirements. Either way, both should be together.
