panic: cannot Rescale: input Ciphertext level is too low [recovered, repanicked]

The bug had a really simple fix (lattigo.bootstrap seems to have lost its level-analysis annotation when we switched from ResetsMulDepthOpInterface to ResetsLevelOpInterface) but really annoying to track down. As a result of the missing level reset annotation, AllocToInplace thought that a mul op after a bootstrap was still happening at basically level 0, so tried to re-use level-0 buffers for them. Lattigo, in its wisdom, would not throw an error upon using a too-small/too-low-level output buffer, but instead just force things down to level 0 and hence in the next step, we'd get an attempt to rescale a level 0 ciphertext 🤦

while i know this is right (hence lgtm).. it broke my compilation of lenet when i patched it :|
