Migrate deap to deap-er

Fresh new install of tpot with python 3.10 crash because of deap with:

```
from tpot import TPOTClassifier
>
raise TypeError, ("Both weights and assigned values must be a "
^
SyntaxError: invalid syntax
```

Deap package seems dead,

Maybe migrate to https://github.com/aabmets/deap-er could be a solution
