SRToolkit missing from requirements

[ogencoglu]

There are imports of SRToolkit in the code. Is this https://github.com/smeznar/SymbolicRegressionToolkit ? It is not listed in requirements.

from SRToolkit.utils.expression_compiler import expr_to_executable_function
from SRToolkit.utils.symbol_library import SymbolLibrary

Great catch, I'll do some checks during the cleanup to make sure all dependencies are accounted for
