missing conversion to large bit integer types

[matthias314]

julia> using EmulatedBitIntegers, BitIntegers

julia> @emulate Int3

julia> Int256(Int3(1))
ERROR: MethodError: no method matching Int256(::Int3)
The type `Int256` exists, but no method is defined for this combination of argument types when trying to construct it.

It's of course debatable whether this should be added (via a weak dependency) to BitIntegers.jl or EmulatedBitIntegers.jl. Wherever it goes, it would be useful functionality.

Tested with Julia 1.12.7, BitIntegers v0.3.7 and EmulatedBitIntegers v0.4.2.

Thanks again, Matthias.

Having the package extension in EmulatedBitIntegers.jl is a bit cleaner in my opinion, because accessing the storage type is a bit more of an internal access than just using the type. But you are right that we could have done it the other way, too.

Please keep the bug reports coming: The package gets better and better with every report from you!
