Dominique Boutigny has discovered that the column type for the _max fields in the instrument table is not large enough for the values we use in obs_lsst - apparently we're not using a 64-bit type, and we never noticed because <sigh> SQLite doesn't care about types.

We should do full audit of all of our integer fields and make sure we chose appropriate sizes for all of them. This may involve switching from just "int" in the dimension configs to more precise types.
