Fix nested access with nested symbol dependency

[alexnick83]

In the Python frontend, when accessing an array from a higher-level scope, we try to "squeeze" the access to begin from index 0 while propagating the correct offset to the edge connecting the outer data to the nested scope (NestedSDFG). To achieve this, any access utilizing a symbol k that is local to the nested scope with an access method f(k) is altered to f(k) - f(min(range(k)) so that it starts from index 0, while the offset f(min(range(k)) is propagated to the outer edge.

However, issues arise when the symbol k range depends on other symbols local to the nested scope. In those cases, the symbols have to be altered/replaced recursively so that no local symbol remains in the offset; otherwise, it is impossible to propagate it to the outer edge, which then starts from index 0, leading to erroneous accesses in the nested scope.

This PR solves the above issue by simply skipping the elaborate and strict squeezing of the local-symbol-dependent sub-ranges when meeting such cases.
