lens 4.3 changelog

(https://hackage.haskell.org/package/lens-4.3.3/changelog)

• Switched the "direction" of the Iso argument to au to match the order generated by makePrisms and makeLenses.
• Removed makeIsos in favor of makePrisms and makeLenses. Each of these functions will construct Isos when appropriate.
• Removed declareIsos in favor of declarePrisms and declareLenses. Each of these functions will construct Isos when appropriate.
• Added matching for type-changing matches with Prisms.
• Added withPrism for recovering the functions passed to prism.
• Added negated, the isomorphism for the negate function.

so code has to change or lens has to be <= 4.3

it works fine with following lens versions

• Lens 4.1.*
• Lens 4.2.*
