Adding jprod_residual! and jtprod_residual!

[AntoninKns]

Adding a workaround of jprod_residual! and jtprod_residual! in order for BundleAdjustmentModels to work better with other packages from JSO. The true detailed version of jprod_residual! and jtprod_residual! should be added later in order to avoid allocations and have better performance for these functions.

I don't think this is a good idea. This is going to be so much slower than what you have now.

@tmigot asked me to add them in case these functions are called by other JSO packages at least it won't crash. I'll let him correct me, I might not have understood the reasons well.

[AntoninKns]

If you think it's worth the time I can directly implement the jprod_residual! and jtprod_residual! manually based on the jacobian description.

I asked Antonin this, so that we can use the package. I get that this is a very basic version (and not efficient), but we can improve it later when Antonin is further advanced with his project.
