Description
The current implementation (as well as the one in LinearAlgebra) calls the balancing function https://github.com/SciML/ExponentialUtilities.jl/blob/dc1e1045590209c18065b7ee3bf909e70e608eb0/src/exp.jl#L24 which we don't have a generic implementation of. It would be great to have one. It shouldn't be a difficult function to implement but might be worth noticing that there is already one available here https://github.com/RalphAS/GenericSchur.jl/blob/master/src/balance.jl

Research direction
Compare the balancing call referenced in ExponentialUtilities.jl's exp.jl with the existing implementation in GenericSchur.jl's balance.jl. Trace how the mutating exp! implementation and LinearAlgebra use balancing, then add a generic implementation and verify that both paths work with generic inputs.
